    • An image forming apparatus is constituted by a rotatable image bearing member; a charging member for electrically charging the image bearing member in contact with the image bearing member; developing member, containing polishing particles, for collecting toner from the image bearing member and effecting development on the basis of an electrostatic latent image formed on the image bearing member; a transfer member for transferring a toner image formed on the image bearing member onto a transfer material; an auxiliary charging member, located downstream from a transfer portion and upstream from the charging member with respect to a movement direction of the image bearing member, for electrically charging toner remaining on the image bearing member after the transfer by contact with the image bearing member; and control means for performing a discharging mode, for discharging polishing particles from the auxiliary charging member onto the image bearing member on the basis of an image ratio of an image to be formed, during non-image formation by applying a voltage to the auxiliary charging member under a condition different from a condition for applying a voltage to the auxiliary charging member during image formation.
    • 图像形成装置由可旋转的图像承载部件构成; 用于使图像承载部件与图像承载部件接触地充电的充电部件; 显影构件,其包含用于从图像承载构件收集调色剂并基于形成在图像承载构件上的静电潜像进行显影的抛光颗粒; 用于将形成在图像承载部件上的调色剂图像转印到转印材料上的转印部件; 辅助充电构件,其相对于图像承载构件的移动方向位于转印部分的下游并且位于充电构件的上游,用于对通过与图像承载构件接触的转印之后剩余在图像承载构件上的调色剂进行充电; 以及用于执行放电模式的控制装置,用于在非图像形成期间,基于要形成的图像的图像比例将辅助充电部件上的研磨颗粒从辅助充电部件排出到辅助充电 在与图像形成期间向辅助充电构件施加电压的条件不同的条件下。
