Abstract

PURPOSE:To apply properly toner to a toner carrier surface by providing a developing powder carrier which carrying developing powder to a developing part, a means of regulating the amount of the developing powder supplied to the developing powder carrier, etc. CONSTITUTION:Developing device 4 has developer carrier 4a which from a toner particle picture. When electric latent image holding surface 1 moves as shown by the arrow, rotating cylindrical sleeve 4b as the developer carrier in the same direction with electronic latent image holding surface apply insulating magentic developer 11 supplied from developer container 12 to the surface of cylindrical sleeve 4b because multipolar permanent magnet 9 is fixed, and further toner particles are charged by the friction between the sleeve surface and toner particles. In addition, arranging a doctor plate closely to the sleeve surface regulates the toner layer thinnly and evenly.
