Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2016180782
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce overlapping of exposure spots formed by light sources adjacent to each other during elimination of electricity to improve efficiency of the elimination of electricity.SOLUTION: An image forming apparatus comprises: solid scanning heads 41 that each expose and eliminate electricity from a surface of each of photoreceptors with a plurality of light emitting devices 41 arranged along a main scanning direction of each of photoreceptor drums 9 having a surface moving in a sub scanning direction; and an image writing control part 38 that divides the plurality of light emitting devices into a plurality of light emitting device groups and controls light emission of the light emitting devices in a time-division manner for each of the light emitting device groups. The image writing control part 38 controls a timing of starting light emission of light emitting devices adjacent to each other so as to reduce the overlapping area of exposure spots formed by the light emitting devices adjacent to each other on the surface of each of the photoreceptors during elimination of electricity from the surface of the photoreceptor drums.SELECTED DRAWING: Figure 5
