Abstract

PURPOSE: To prevent deposited toner from peeling from electrode surface and contaiminating copying paper by finishing the aluminum-made developing electrode of a wet type PPC copying machine to surface roughness sufficiently coarser than that of the rolling surface of a smoothing roll.
CONSTITUTION: In plain paper electrostatic copying of wet type developing, the toner having deposited on the developing electrode sometimes peels at one time, deposits on the photosensitive drum, are transferred and mark black stained spots on copying paper. Developing solution containing toner is filled in a developing device 2 which is a tank provided with the device for injecting the developing solution between the developing electrode plate 3 disposed along the circumference of the drum 1 toward the drum 1. If the surface of the developing electrode plate 3 on the side opposing to the drum 1 is sufficiently roughened through sandblasting or the like, the adhesiveness between the toner and electrode becomes better and the peeling down of a large amount of toner at one time is prevented.
