ABSTRACT:
An image forming apparatus includes a control unit for executing a control operation in which the photoreceptor drum is not to directly contacted with a divided holding region surface on the transfer belt onto which a transfer sheet fed again by the trayless device is held. In the control operation, the two-sided image formation is previously conducted on the transfer sheets, the number of which corresponds to the surplus number (2) obtained when the number (7) of transfer sheets of continuous two-sided image formation is divided by the number (5) of the divided holding regions (panels) on the transfer belt passing through a transfer position on the photoreceptor drum in a period of time from when a transfer sheet, onto the first image surface of which an image is formed, is held on the transfer belt to when the transfer sheet is fed again to the transfer belt via a transfer sheet conveyance passage of the trayless mechanism, and then the two-sided image formation is conducted on the residual number (7-2=5) of transfer sheets.
