PROBLEM TO BE SOLVED: To achieve soft pressure-contact development and to form an image which is high in resolution and less in density fluctuation. SOLUTION: A supply member 26 is disposed in pressure contact with a toner carrier 32 having hardness greater than that of the supply member 26 but not greater than specific hardness, and is rotated and driven in the same direction as the toner carrier 32, thereby stripping and supplying toner 7. By pressing a plate-spring-like regulation member 35 against the toner carrier 32, the toner 7 is electrified to a specific polarity and also is formed into about one to two thin layers. This makes it possible to provide the developing device which is capable of soft pressure-contact development, the formation of an image with high resolution and less density-change, and is small and inexpensive. |
