ABSTRACT:
An image forming apparatus is provided with a rotatable photosensitive member; an imaging assembly for exposing the surface of the photosensitive member to light so as to form an electrostatic latent image thereon and developing the electrostatic latent image; and a sensor arranged in the vicinity of and opposed to the surface of the photosensitive member, and adapted for detecting an imaging performance in a specific region on the surface of the photosensitive member. With the image forming apparatus thus constructed, measurement values vary only within a reduced range since an imaging performance of the photosensitive member is detected in a specific region on the photosensitive member.
