发明名称 IMAGE FORMING APPARATUS
摘要 A pixel distance corrector configured to correct a pixel distance in the main scanning direction so that latent images corresponding to each pixel of image data are formed on the surface of the photosensitive member at substantially equal intervals in the main scanning direction. A controller configured to control a light source to emit light with a first light emission luminance with respect to an image part of the photosensitive member, and a second light emission luminance which is lower than the first light emission luminance, with respect to a non-image part of the photosensitive member. The controller is configured to correct light emission luminance so that the second light emission luminance decreases as the scanning speed decreases.

主权项 1. An image forming apparatus including a photosensitive member irradiated based on image data by a light source configured to emit laser light, and a deflector configured to deflect the laser light so that the laser light moves over a surface of the photosensitive member in a main scanning direction, wherein a scanning speed at which the laser light moves over the surface of the photosensitive member in the main scanning direction is not constant, the image forming apparatus comprising: a pixel distance corrector configured to correct a pixel distance in the main scanning direction so that latent images corresponding to each pixel of the image data are formed on the surface of the photosensitive member at substantially equal intervals in the main scanning direction; and a controller configured to control the light source emit laser light with a first light emission luminance with respect to an image part of the photosensitive member, and a second light emission luminance which is lower than the first light emission luminance, with respect to a non-image part of the photosensitive member, wherein the controller is configured to correct light emission luminance so that the second light emission luminance decreases as the scanning speed decreases.
