Original Abstract Submitted
an image forming apparatus includes a photosensitive member, a charging member, a charging voltage applying portion, an exposure unit, a developing member, a developing voltage applying portion, a transfer member, a transfer voltage applying portion, and a controller. in a discharging operation, an exposure surface is formed on a photosensitive member surface by exposing the photosensitive member surface to light by the exposure unit. the controller carries out control so that: a developing voltage on a side of a predetermined polarity relative to an exposure surface potential is applied to the developing member; a transfer voltage less than a discharge start voltage in absolute value of a potential difference between itself and the exposure surface potential of the is applied to the transfer portion; and a charging voltage on the side of the predetermined polarity relative to the exposure surface potential is applied to the charging member.
