Abstract

PURPOSE:To supply a developer to a magnetic roll part uniformly to use a small quantity of the developer effectively, by providing a member, which guides the developer to deflect it to one side in the longitudinal direction, and a member which carries this collected developer to the other side. CONSTITUTION:The bottom part in a casing is a developer storing part, and a developer T is stored in this part, and a developer agitating member 4 and a fogger roll 5 which feeds the developer in the casing toward one end part in the longitudinal direction of the casing are provided. The second fogger roll 6 is arranged above the roll 5 approximately in parallel with the roll 5, and a blade 7 for scraping off the developer which is not transferred to the photoreceptor side by a developing member and remains is brought into contact with the surface of a sleeve 2. These rolls 5 and 6 are so rotated that their toner feed directions are opposite to each other.
