ABSTRACT:
A replenishing device for replenishing toner to a developing device for developing electrostatic latent images includes a hopper, and a toner conveying screw disposed in the hopper along a bottom surface of the hopper. The bottom surface consists of an inclined surface that rises in a downstream direction relative to the direction in which the screw conveys toner, so that an interior height dimension of the hopper at an end portion that is located upstream in the toner conveyance direction is greater than an interior height dimension at an end portion that is located downstream in the toner conveyance direction.
