Abstract

PURPOSE:To attach uniform toner on a developing drum, by oppositing a developing agent amount restricting member made of a permanent magnet to a developing drum not using a permanent magnet. CONSTITUTION:A one-contact developing agent D attached with a development drum 3 with the developing agent carrying function with coarse surface is restricted with a spare restricting blade 9 and is subject to be separated for excessive toner with a restricting mechanism 6 turned reversingly to the developing drum 3 and carried to the developing region opposing to a photoreceptor 1. In this case, since the restricting mechanism cosists of a permanent magnet and the developing drum 3 opposing to it has no magnet, the restriction of amount of toner can be made in excellent manner by adjusting the interval of the both and the strength of the magnetic force.
