Abstract: An image forming apparatus capable of preventing image defects, such as color shift, from being caused, by preventing increased transfer pressure from being applied by a primary transfer section to thereby prevent a surface speed difference from being generated between the photosensitive drum and the intermediate transfer belt. The image forming apparatus includes a photosensitive drum and an intermediate transfer belt that rotates in contact with the photosensitive drum, respective brushless DC motors for driving the photosensitive drum for rotation and the intermediate transfer belt for rotation, and a controller for controlling the brushless DC motors. The controller performs control such that the brushless DC motor applies assist torque to the photosensitive drum, for offsetting load torque acting thereon, thereby enabling the photosensitive drum to be friction-driven by the intermediate transfer belt.
