ABSTRACT:
A developing device for use with an image forming apparatus can properly detect a residual toner level by adjusting the toner diffusion in a toner cartridge. The developing device stirs toner in the toner cartridge by rotating an agitator in the toner cartridge, and supplies the stirred toner from a toner introduction port. The image forming apparatus then forms images by electrophotographic processes. The agitator has at least two elastic film members and is formed so that the first film member is rotated first, then the second film member is rotated by following the first film member.
