Abstract
An image forming apparatus includes transferring current to the transfer portion; a cleaning blade, provided downstream of a transfer portion and upstream of an image forming station with respect to a rotational moving direction of an intermediary transfer member, for removing toner from the intermediary transfer member; an executing portion for executing an operation in a cleaning mode for removing the toner by the cleaning blade, in which a cleaning current is applied to a transfer portion in a direction opposite to that of an image transferring current to shift the toner from the transfer roller onto the intermediary transfer member; and a controller for setting the cleaning current, in which the set cleaning current is lower when a cumulative number of fed recording materials from the execution of the previous cleaning mode is larger.
