IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes exposing units, a photoconductor, developing units, a processor, and a memory storing instructions. Each exposing unit includes light emitting elements arranged in a main scanning direction and divided into blocks each illuminating at a corresponding light emitting time point. The instructions cause the image forming apparatus to: change a light emitting time point for one of two blocks contained in respective two exposing units at the same position in the main scanning direction, to reduce an image distance in a sub-scanning direction between two images each to be formed by illumination of at least one light emitting element contained in a corresponding one of the two blocks; illuminate the light emitting elements of each of the exposing units at light emitting time points including the light emitting time point obtained by the change; and develop electrostatic latent images formed on the photoconductor.

1. An image forming apparatus, comprising:
a plurality of exposing units each comprising a plurality of light emitting elements arranged in a main scanning direction, the plurality of light emitting elements being divided into a plurality of blocks each containing at least one light emitting element, all of the at least one light emitting element illuminating at a light emitting time point set for said each of the plurality of blocks; a photoconductor; a plurality of developing units each comprising a developing material of a set specific color; a processor; and a memory storing a plurality of instructions, the plurality of instructions, when executed by the processor, cause the image forming apparatus to execute:
a first change processing in which the image forming apparatus makes a change in a light emitting time point for one of two blocks contained in respective two exposing units of the plurality of exposing units and located at an identical position in the main scanning direction, such that an image distance which is a distance in a sub-scanning direction between two images each to be formed by illumination of at least one light emitting element contained in a corresponding one of the two blocks at a corresponding one of light emitting time points is less when the at least one light emitting element illuminates at a light emitting time point obtained by the change than when the at least one light emitting element illuminates at a light emitting time point which is not changed by the change;an illuminating processing in which the plurality of light emitting elements of each of the plurality of exposing units illuminate at light emitting time points comprising the light emitting time point obtained by the change in the first change processing; anda developing processing in which each of electrostatic latent images formed on the photoconductor in the illuminating processing is developed with a developing material of the set specific color which is comprised in a corresponding one of the plurality of developing units.
