Summary:To provide an image forming apparatus that reduces the likelihood of the occurrence of image defects, while preventing the occurrence of stripe-like scratches in a circumferential direction of an image carrier.SOLUTION: An image forming apparatus comprises: an image carrier; an electrifying device; an exposure device; a developing device; transfer means; a cleaning blade that is brought into pressure contact with an outer peripheral surface of the carrier to remove a residual toner on the image carrier; a temperature and humidity detection device that detects the temperature and humidity on the periphery of the image carrier; a driving mechanism that reciprocates the image carrier or the cleaning blade along a rotation axis direction; and a control unit that executes the reciprocation when the temperature and humidity on the periphery of the image carrier detected by the temperature and humidity detection device are equal to or less than predetermined values.SELECTED DRAWING: Figure 6 【課題】像担持体の周方向に筋状の傷が発生するのを抑制しつつ、画像不良が生じにくい画像形成装置を提供する。【解決手段】画像形成装置は、像担持体と、帯電装置と、露光装置と、現像装置と、転写手段と、担持体の外周面に圧接され像担持体上の残留トナーをクリーニングするクリーニングブレードと、像担持体周辺の温度および湿度を検知する像担持体、またはクリーニングブレードを回転軸方向に沿って往復移動させる駆動機構と、温湿度検知装置により検知された像担持体周辺の温度、および湿度が所定値以下のときに往復移動を実行する制御部と、を備える。【選択図】図６
