置。[Claims for Utility Model Registration] (1) Transferring the toner image on the photoreceptor to a recording paper interposed between the photoreceptor and a transfer conveyor belt wrapped between a pair of rollers; In a transfer conveyance device that conveys the subsequent recording paper by attracting it to a belt, a transfer conveyance device is provided in the body that supports the pair of rollers and is movable angularly around the axis of one of the rollers located at a position far from the photoreceptor. a support member; a means for driving the one-sided roller; a cam rotatably provided on the support member; and a support member provided on the machine body side and in sliding contact with the cam; On the other hand, such a cam means displaces the roller at a low speed when moving away from the photoreceptor and at a high speed when approaching the photoreceptor, and detects the recording paper being conveyed between the belt and the photoreceptor. After the recording paper is detected by the detection means, the recording paper is held between the belt and the photoreceptor by the cam means during the transfer period, and during the period when no transfer is performed,
1. A transfer conveyance device comprising: drive control means for separating the belt from a photoreceptor. (2) The one roller is constantly driven to rotate, and the drive control means includes a clutch that transmits and interrupts the power of the one roller, and a power transmission means that transmits the power from the clutch to the cam to rotate the cam. A transfer conveyance device according to claim 1, which is characterized in that:
