Abstract:
1. An image forming apparatus comprising: an image bearing member configured to be rotatable; an intermediate transfer member configured to be rotatable in contact with said image bearing member; a first drive unit configured to drive said image bearing member for rotation; a second drive unit configured to drive said intermediate transfer member for rotation; and a control unit configured to control said first drive unit and said second drive unit, wherein said control unit performs control so that said first drive unit is caused to apply torque to said image bearing member, for offsetting load torque acting on said image bearing member, to thereby cause said image bearing member to be friction-driven by said intermediate transfer member, and wherein said control unit controls said first drive unit to apply an assist torque to said image bearing member, for setting a friction state between said image bearing member and said intermediate transfer member when said image bearing member is friction-driven by said intermediate transfer member to a static friction state.
