Summary:PROBLEM TO BE SOLVED: To provide an image formation control device that is provided in an image forming apparatus comprising an image carrier and a charging part, and supplies a proper amount of lubricant to the image carrier.SOLUTION: An image formation control device determines whether the amount of drive T of a photoreceptor drum is equal to or more than a preset amount of drive Tr (S601), applies a voltage value V to a charging roller when T≥Tr (S603), measures a current value I of a charging current and ambient temperature and humidity (S604 and S605), acquires VI characteristics on the basis of the measurements (S606), estimates a charging gap (S607), sets the amount of lubricant to be supplied according to the size of the estimated charging gap (S608), and controls the amount of lubricant to be supplied on the basis of the set value.SELECTED DRAWING: Figure 6 【課題】像担持体と帯電部とを備える画像形成装置において、像担持体に適正量の潤滑剤を供給する画像形成制御装置を提供する。【解決手段】画像形成制御装置は、感光体ドラムの駆動量Ｔが予め設定されている駆動量Ｔｒ以上であるか否かを判定しＳ６０１、Ｔ≧Ｔｒのとき、電圧値Ｖを帯電ローラに印加しＳ６０３、帯電電流の電流値Ｉと周辺の温湿度とを計測しＳ６０４-Ｓ６０５、これに基づきＶＩ特性を取得しＳ６０６、帯電ギャップ推定しＳ６０７、推定された帯電ギャップの大きさに応じて潤滑剤の供給量を設定しＳ６０８、設定値に基づいて潤滑剤の供給量を制御する。【選択図】図６
