Abstract
The present invention relates to an image forming apparatus in which an electrostatic latent image is formed on an electrophotographic photosensitive member with digital light, and electrostatically developed with a developer to form a developed image. The apparatus has an exposure device for normally increasing the reflection density only in a specified region on the photosensitive member in a white image portion where no image is basically formed, in the horizontal scanning direction of the digital light. For example, a small amount of developer is supplied to either end of the photosensitive member having the tendency that the amount of the developer supplied is small, thereby preventing the occurrence of image flow at either end.
