Image-forming apparatus and controller

Abstract

The present disclosure provides an image-forming apparatus and a controller. The image-forming apparatus includes a photosensitive member; a scanning unit, configured to perform laser scanning on the photosensitive member at a non-constant linear speed along a main scanning direction to form an electrostatic latent image; and includes a controller, configured to make a first scanning period corresponding to a first pixel at a central region of the photosensitive member to be not equal to a second scanning period corresponding to a second pixel at a non-central region of the photosensitive member. The first pixel and the second pixel are each configured with a light-emitting time period and a non-light-emitting time period; and the light-emitting time period satisfies that a light-emitting time length of the light-emitting time period of the first pixel is same as a light-emitting time length of the light-emitting time period of the second pixel.

Dependencies are inferred from the claim text.
