Abstract
An image forming apparatus includes a photosensitive member, an exposure device for exposing the photosensitive member which has been charged, a storing device storing therein a characteristic table two-dimensionally representing the potential decay characteristic of the surface of the photosensitive member, and a control device for controlling the exposure device on the basis of the characteristic table stored in the storing device.
Claims17
An image forming apparatus comprising:
- a photosensitive member;
- exposure means for exposing said photosensitive member which has been charged;
- storing means storing therein a characteristic table two-dimensionally representing a potential decay characteristic of a surface of said photosensitive member;
