Abstract
In an image forming apparatus including a transfer member that primarily transfers a developer image from an image bearing member onto an intermediate transfer belt by applying an electric current to an intermediate transfer belt in a circumferential direction, a control unit which executes a first mode in which to rotate the intermediate transfer belt and a second mode in which to rotate the intermediate transfer belt at a rotation speed higher than that in the first mode. The control unit performs control such that an absolute value of a second voltage to be applied to the transfer member in a case of performing primary transfer in the second mode is less than an absolute value of a first voltage to be applied to the transfer member in a case of performing the primary transfer in the first mode.
