In an electrophotographic (EP) printer, a rotatable member includes a deposition area and a non-deposition area. A toner supply supplies toner to the member, and a moving receiving member receives from the deposition area of the rotatable member while the rotatable member rotates. The rotatable member is cleaned with a selectively-retractable blade in mechanical contact with the member so that toner is removed from the deposition area while the rotatable member rotates. An artifact sensor automatically detects a toner image artifact on the receiver. A controller responsive to the artifact sensor causes the blade to retract when an artifact is detected, and a blade cleaner cleans the blade while the blade is not in mechanical contact with the member.

An image forming apparatus has a function for adjusting the position at which a toner image is formed on a printing material, based upon amount of light reflected from a toner image that has been formed on an image carrier. The light-emitting unit emits light that irradiates the image carrier, and the detecting unit detects an amount of substrate-light reflected from the substrate of the image carrier. The determining unit determines whether the difference between the amount of substrate-light detected at a first point in time and the amount of substrate-light detected at a second point in time later than the first point in time is greater than a predetermined threshold value. The light-power control unit increases the amount of light in the light-emitting unit if the difference is greater than the predetermined threshold value.

The data, saved to a secure database, can be processed and calculated quantities can be derived from the field of binary data, which can be affixed to the document or manufactured part that the stamp is affixed to. The regular array can be read out by scanner, quantities calculated, and compared to the values printed on the part or document. Additionally, the regular array can be read out by optical scanner and parts or all of the data compared to the data stored in the secure database.

An image forming apparatus for detecting surface conditions of a recording sheet on which an image is formed, includes a light source configured to emit a first light beam and a second light beam, an image capture device configured to capture a first image of a surface of the recording sheet illuminated with the first light beam and a second image of the surface of the recording sheet illuminated with the second light beam. A first straight line including a ray in a center of the first light beam and a second straight line including a ray in a center of the second light beam intersect with each other, when each straight line is projected onto the surface of the recording sheet, and a detection device configured to detect information about the unevenness on the surface of the recording sheet based on the first image and the second image.

An image forming device includes: a main body; a photosensitive body; a retaining member; an endless belt; a first cleaning member; a belt side conveying unit; a retaining member side conveying unit; and a receptacle. The retaining member retains the photosensitive body and is movable between an internal position and an external position. The endless belt contacts the photosensitive body when the retaining member is in the internal position and separates from the photosensitive body when the retaining member is in the external position. The first cleaning member is fixedly positioned and removes deposited matter on the endless belt. The belt side conveying unit is provided in the main body and conveys the deposited matter removed by the first cleaning member. The retaining member side conveying unit is provided in the retaining member and conveys the deposited matter conveyed by the belt side conveying unit to the receptacle. 1. An image forming device comprising:a main body;a photosensitive body on which a developer image is formable;a retaining member configured to retain the photosensitive body and be movable between an internal position inside the main body and an external position outside the main body;an endless belt configured to contact the photosensitive body when the retaining member is in the internal position and separate from the photosensitive body when the retaining member is in the external position;a first cleaning member fixedly positioned and configured to remove deposited matter on the endless belt;a receptacle configured to be detachably mounted in the retaining member and store the deposited matter removed by the first cleaning member; anda conveying unit configured to convey the deposited matter removed by the first cleaning member into the receptacle; a belt side conveying unit provided in the main body and configured to convey the deposited matter removed by the first cleaning member; and', 'a retaining member side conveying unit provided in ...
