<p>PURPOSE: To form a stable image without fogging, scattering of toner, etc., with recycling development by relaxing the rapid decrease of the electrostatic charge quantity of a developer caused by the incorporation of recovered toner. CONSTITUTION: In the recycling developing method, an electrostatic charge image formed on a photoreceptor 1 is developed with a start developer filled into a developing unit 11, to form a toner image, which is transferred to a prescribed paper sheet and recovering the toner remaining on the photoreceptor 1 by a cleaning means, and the development is repeated while supplying virgin toner and the toner recovered by the cleaning means to the developing unit 11. The average charge quantity of the toner in the developer contg. the recovered toner is set larger than that in the start developer by >=10μC/g to attain the recycling development.</p> |
