发明名称 IMAGE FORMING APPARATUS
摘要 An image forming apparatus including a cleaning member having a belt cleaning blade and a conductive brush. A value of a charging current that is generated when charging residual toner with the conductive brush is smaller when a color mode is executed compared to that when a monochrome mode is executed.

主权项 1. An image forming apparatus comprising: a plurality of image carrying members that each carry a toner image; an intermediate transfer body that is capable of moving while abutting against the image carrying members, the toner image of each image carrying member being primarily transferred onto the intermediate transfer body; a cleaning member that includes an abutting member that scrapes off residual toner that remains on the intermediate transfer body without being secondary transferred to a transfer material from the intermediate transfer body, anda charging member that is positioned downstream of the abutting member in a moving direction of the intermediate transfer body and that charges the residual toner that has passed through the abutting member; and a control unit that is capable of executing a first mode in which a toner image is primary transferred from each of the plurality of image carrying members to the intermediate transfer body, anda second mode in which a toner image is primary transferred from a single image carrying member among the plurality of image carrying members to the intermediate transfer body, wherein the control unit controls a value of a charging current that is generated when charging the residual toner with the charging member such that the value when the first mode is executed is smaller than the value when the second mode is executed.
