Abstract:
An image forming apparatus includes a rotatable image bearing member; an intermediate transfer member which makes contact with the image bearing member and bears a toner image transferred from the image bearing member; a first driving means which transmits driving to the intermediate transfer member; and a second driving means which transmits driving to the image bearing member when a rotating speed of the image bearing member is lower than a predetermined speed, wherein a rotating speed of the rotatable image bearing member is faster than the predetermined speed by receiving a rotating friction force from the intermediate transfer member.
