Filed: 1981-10-31
Abstract: PURPOSE:To prevent fogging even if a developer has a reverse polarity owing to its deterioration, by providing a rectifying layer on the external surface of a supply member for supplying the developer. CONSTITUTION:A nonmagnetic sleeve 27 rotates as shown by an arrow, and on its external suface, a semiconductor layer 28 as a rectifying layer is formed.
