Abstract
An image forming apparatus is configured to execute a first image forming mode, in which an image is formed by forming toner images on a first photosensitive member and a second photosensitive member, and a second image forming mode, in which an image is formed by releasing the first photosensitive member from an outer peripheral surface of an intermediate transfer member and bringing the second photosensitive member into abutment against the outer peripheral surface of the intermediate transfer member. A control unit is configured to set a potential difference, which is a difference between an absolute value of a dark point potential of the second photosensitive member and an absolute value of a direct current component of a developing bias, to be lower in a case of the second image forming mode than in a case of the first image forming mode.
