IMAGE FORMING APPARATUS AND CONTROL PROGRAM

To provide an image forming apparatus that can prevent excessive correction without impairing the followability of correction to color change.SOLUTION: An image forming apparatus 100 comprises: an image forming unit 20 that forms a patch for correction by using toner; a measuring unit 50 that measures the color, density or amount of toner attached to the patch for correction; a calculation unit that calculates a reference correction amount based on a measured value from the measuring unit 50 so as to adjust the density of the patch for correction to a target value; and a correction unit that corrects an image formation condition for the image forming unit 20 by a first correction amount smaller than the reference correction amount.SELECTED DRAWING: Figure 1 【課題】色変動への補正の追随性を損ねることなく、過補正を抑制可能な画像形成装置を提供する。【解決手段】画像形成装置１００は、トナーを用いて補正用パッチを形成する画像形成部２０と、補正用パッチの色、濃度、または、トナー付着量を測定する測定部５０と、測定部５０の測定値に基づいて、補正用パッチの濃度が目標値となるように基準補正量を算出する算出部と、基準補正量よりも少ない第１補正量だけ画像形成部２０の作像条件を補正する補正部とを備える。【選択図】図１
