PURPOSE:To reduce the size of a toner storing device of an electrostatic photographing device by forming a toner storage on a photosensitive drum to supply toner to a developing roller and separating the recovered toner from unused toner to stay the recovered toner on the photosensitive drum. CONSTITUTION:A toner storing room 31 is formed on a fixed shaft 22 of the photosensitive drum 2 and toner is supplied to the developing roller through a toner carrier 42 provided with a toner discharging motor coil 43. On the other hand, the recovered toner obtained after development is similarly carried through a recovered toner carrier 46 and recovered in a recovered toner storage 30 on the drum so as to be separated from unused toner. Consequently, is unnecessary to form containers for storing the unused toner, recovered toner, etc., so that the toner storing device of the electrostatic photographing device can be reduced at its size. |
