Abstract:
1. An image forming apparatus comprising: an exposure unit configured to form a latent image on an image bearing member; a development unit configured to develop the latent image to form a toner image; a primary transfer unit configured to transfer the toner image formed on the image bearing member to an intermediate transfer medium; a secondary transfer unit configured to transfer the toner image transferred to the intermediate transfer medium to a sheet; a first drive unit configured to rotate the image bearing member; a second drive unit configured to rotate the intermediate transfer medium; and a control unit configured to control said first and second drive units so that a peripheral velocity difference between the image bearing member and the intermediate transfer medium becomes a first value at starting, and configured to control said first and second drive units so that the peripheral velocity difference becomes a second value larger than the first value when minute toner, which is not recognized as an image and is adhered to the image bearing member by starting said development unit, reaches the position of said primary transfer unit.
