A recording apparatus includes a conveyance mechanism, a sticking section and an adjustment section. The conveyance mechanism has an adhesive belt on which a recording medium is placed, and configured and arranged to intermittently convey the recording medium. The sticking section is configured and arranged to apply pressure to the recording medium to stick the recording medium to the adhesive belt. The adjustment section is configured and arranged to adjust a pressure force applied by the sticking section to the recording medium. The adjustment section is configured and arranged to change the pressure force so that the pressure force during conveyance of the recording medium is greater than the pressure force during stopping of the recording medium. 1. A recording apparatus comprising:a conveyance mechanism having an adhesive belt on which a recording medium is placed, and configured and arranged to intermittently convey the recording medium;a sticking section configured and arranged to apply pressure to the recording medium to stick the recording medium to the adhesive belt; andan adjustment section configured and arranged to adjust a pressure force applied by the sticking section to the recording medium, the adjustment section being configured and arranged to change the pressure force so that the pressure force during conveyance of the recording medium is greater than the pressure force during stopping of the recording medium.2. The recording apparatus as set forth in claim 1 , whereinthe adjustment section includes a rotating section configured and arranged to rotate in tandem with the recording medium being conveyed.3. The recording apparatus as set forth in claim 1 , whereinthe adjustment section is configured and arranged to control the pressure force of the sticking section so as to reduce a difference between: a product of the pressure force and pressure time applied per unit surface area during the stopping of the recording medium associated with the ...
