Patent ID: 8145084

Claim:
An image forming apparatus comprising: an image bearing member configured to bear a toner image and move; a transfer member configured to form a nip with the image bearing member and move; and a control device configured to control a moving speed of the transfer member, wherein a transfer material is conveyed through the nip and the toner image on the image bearing member is transferred on the transfer material, wherein the image forming apparatus has a marginless mode in which the toner image is formed on said image bearing member in an area that covers the transfer material and an area outside the transfer material, and wherein, at least in a case where the toner image is transferred onto a leading edge of the transfer material in a transfer material conveyance direction in the marginless mode, the control device controls, at least while the leading edge of the transfer material is passing through the nip, the moving speed of the transfer member so that a conveyance speed of the transfer material becomes slower than the moving speed of the toner image on the image bearing member passing through the nip.
