Zusammenfassung:To provide an image forming apparatus designed for further power saving.SOLUTION: An image forming apparatus (1) comprises: a polygon mirror for deflecting a light beam in a direction toward a photoreceptor; a polygon motor (21) that drives to rotate the polygon mirror; a motor driver IC (39) that controls the rotation drive of the polygon motor (21); an SoC (36) that outputs a D-Sleep signal representing whether the image forming apparatus is in a deep sleep mode, and controls the motor driver IC (39); a low voltage power supply (26) that outputs low voltage; and an on/off circuit (38) that, when receiving input of the D-Sleep signal representing that the image forming apparatus is not in the deep sleep mode, outputs low voltage to the motor driver IC (39), and when receiving input of the D-Sleep signal representing that the image forming apparatus is in the deep sleep mode, does not output low voltage to the motor driver IC (39).SELECTED DRAWING: Figure 2 【課題】更なる省電力に対応した画像形成装置を提供する。【解決手段】画像形成装置(1)は、光ビームを感光体に向かう方向へ偏向するためのポリゴンミラーと、ポリゴンミラーを回転駆動するポリゴンモータ(21)と、ポリゴンモータ(21)の回転駆動を制御するモータドライバIC(39)と、ディープスリープモードであるか否かを表すD-Sleep信号を出力し、モータドライバIC(39)を制御するSoC(36)と、低電圧を出力する低電圧電源(26)と、ディープスリープモードでないことを表すD-Sleep信号が入力される場合、低電圧をモータドライバIC(39)に出力し、ディープスリープモードを表すD-Sleep信号が入力される場合、低電圧をモータドライバIC(39)に出力しないオンオフ回路(38)と、を備える。【選択図】図2
