Abstract
An image forming apparatus includes a member (drum), a charging device, an exposure device, a developing device, a transfer device, a cleaning blade, a selecting device for selecting an execution mode from an image forming mode and a recovery mode, and a controller for controlling a peak-to-peak voltage applied to the charging device in the operation in the recovery mode. When the recovery mode is selected, the controller effects control so that a band-like toner image is formed on the drum and is supplied to the cleaning blade and so that a peak-to-peak voltage of the AC voltage larger than that of the AC voltage applied to the charging device in the operation in the image forming mode is applied to the charging device in a predetermined period after a leading end of the band-like toner image subjected to removal by the cleaning blade passes through the charging device.
