Image forming apparatus with changing photosensitive member speed

摘要

There is provided an image forming apparatus in which an image forming speed is changed in a state where toner is provided between a photosensitive drum and an intermediate transfer member. Therefore, even if a speed difference between the photosensitive drum and the intermediate transfer member is generated, a drive torque can be suppressed, and deterioration caused by abrasion of the photosensitive drum and the intermediate transfer member can be reduced.

1. An image forming apparatus comprising:
a photosensitive member on which a latent image is formed; a development unit configured to develop the latent image formed on the photosensitive member as a toner image; a rotating member on which the toner image formed on the photosensitive member is transferred, wherein the toner image is transferred on the rotating member at a nip portion where the rotating member contacts the photosensitive member; and a control unit configured to control speeds of the photosensitive member and the rotating member, wherein the control unit changes the speeds of the photosensitive member and the rotating member in a state where toner exists at the nip portion, and wherein, for changing the control speed from a first speed to a second speed, the control unit makes a toner to exist on the nip portion by providing the toner from the developing unit to the photosensitive member.
