A photosensitive member refreshing device includes an image bearing member, an exposure device, a developing device, a detecting section, a cleaning section, and a control section. The image bearing member has a photosensitive roller rotatable about a rotation axis. The exposure device exposes the photosensitive roller to light according to an exposure pattern. The developing device supplies a toner to the photosensitive roller to form a toner image corresponding to the exposure pattern on the photosensitive roller after the exposure device has exposed the photosensitive roller to light. The detecting section detects the toner image on the image bearing member. The cleaning section cleans a surface of the photosensitive roller. The control section controls the exposure pattern based on a result of detection by the detecting section.
