Claim:
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; and a controller configured to execute: wherein the plurality of exposing units are at least three exposing units, wherein the at least three exposing units respectively comprise at least three blocks located at an identical position in the main scanning direction, and wherein the controller is configured to execute a switch processing in which the controller switches between (i) a first mode in which the controller executes the first change processing and does not execute the second change processing for the at least three blocks and (ii) a second mode in which the controller executes the second change processing and does not execute the first change processing for the block of the first exposing unit among the at least three blocks, and the controller executes the first change processing for the at least three blocks other than the block of the first exposing unit.
