Abstract

PURPOSE:To obtain sharp images by providing a rotating member which rotates integrally or synchronously with a rotary magnet roll provided in a developing device, a synchronizing signal generating means that take out the synchronizing signal from said rotating member, etc. CONSTITUTION:A biasing devide for developing is provided with a magnet roll 11, a rotating member 12 which rotates integrally or synchronously with the roll 11, a synchronizing signal generating means 13 that take out the synchronizing signal from the member 12, etc. After the one component magnetic developer in a toner replenishing part 31 is regulated by an earing regulating part 32, it is conveyed by the rotating roll 11 and a developing sleeve 21, and is developed by a developing soln. 24. In this case, the voltage in the direction where the projecting developer is drawn in is applied to the earing parts by magnetic force in synchronization with the sleeve 21, whereby the sharp images having no photographic fogs are obtained.
