SOLUTION: The developing device includes a developing tank that stores developer, a developing roller formed from a rubber roller, a supply sponge roller, and a stirring cooperation member located above it. The developing device supplies developer from the developing tank to the developing section, while stirring developer by rotating the stir cooperation member within the developing tank. The developing tank has a coil spring having a spiral structure that is fixed on the stir cooperating member, at lengthwise both ends, below a developer supply port and that differs in coil structure between the end sides and the center side. When the stir cooperating member rotates and is brought into contact with the coil spring, the coil spring causes falling of developer accumulating on the coil spring. COPYRIGHT: (C)2010,JPO&INPIT
