PROBLEM TO BE SOLVED: To provide a toner layer regulating member capable of abutting on a rotating toner carrier with uniform contact pressure, forming a toner layer in uniform thickness, uniformly triboelectrifying toner and providing a high- quality image free from irregular developing density and image defect. SOLUTION: The plate-like toner layer regulating member for uniformly forming the toner layer on the toner carrier and triboelectrifying the toner is constituted by sticking a rubber elastic film 21 on a rigid base plate 20 and further sticking a triboelectrifying film 22 having a reverse polarity to the triboelectrification polarity of the toner to the surface of the film 21. In the developing device, the tip of the toner layer regulating member is held to abut on the surface of the toner carrier. |
