Abstract
A color printer including, a conductive brush roller to contact a photosensitive drum at a position downstream of a transferring apparatus and upstream of a charging apparatus, wherein at least part of residual toner is collected after temporarily transferring on the photosensitive drum, and the collected toner is expelled onto the photosensitive drum, a charge electrode facing the brush roller at a position other than the contact position of the photosensitive drum and the brush roller, and a power source to apply voltage to the charge electrode, wherein the polarity of the voltage applied from the power source to the charge electrode with respect to the average voltage of the surface of the photosensitive drum after transferring is the same as a charging polarity of the toner at developing.
