Abstract

PURPOSE:To improve the operation of a device by permitting a means of applying insulating magnetic developing powder to a developing power carrier to serve as a means of removing the developing power from a carrier with a latent image. CONSTITUTION:Cleaning device 4 serving as a developing device has developing powder carrying means 4b and cleaning means 4a for removing toner on electrostatic image holder 1 serving as a means of applying the developing powder to means 4b, and a toner powder picture is formed according to an electrostatic image on photoreceptor 1. Device 5 transfers the toner image to transfer material 6, and device 7 is a fixing device for fixing the toner image on member 6 to be transferred and consists of at least two rollers with a pressurizing or heating and pressurizing means. After the transfer, the remaining toner on image holder 1 is removed by cleaning means 4a having a magnetic brush formed of the toner in developing device 4.
