Image forming apparatus having transfer material bearing member.

摘要

The present invention provides an image forming apparatus comprising an image bearing member (2) for bearing an image, and a transfer material bearing member (1) rotatable for bearing a transfer material (14). Wherein the image on the image bearing member (2) is transferred onto the transfer material born by the transfer material bearing member (1) at a transfer position (Ptr), and a voltage is applied to the transfer material bearing member (1) during the transferring of the transfer material. It is characterized by that, when a distance between the transfer position (Ptr) and a separation position (Psep) where the transfer material is separated from the transfer material bearing member (1) along a peripheral surface of the transfer material bearing member (1) in a rotational direction of the transfer material bearing member is L, a whole circumferential length of the transfer material bearing member (1) is L1 and a maximum length of the transfer material (14) usable in the image forming apparatus in the rotational direction of the transfer material bearing member is Hmax, a relation L </= (L1 - Hmax) is satisfied. <IMAGE>
