ABSTRACT:
A developing apparatus usable with an electrophotographic image forming apparatus, the apparatus including a developer accommodating container, a developer chamber including a developer carrying member carrying and feeding a developer supplied from the container to develop an electrostatic latent image formed on an electrophotographic photosensitive member, a stirrer stirring the developer in the chamber and supplying the developer from the container into the chamber through an opening in the container, a wall surface, provided in the container, for being contacted by a free end portion of the stirrer while the stirrer moves, and a detector detecting a remaining amount of the developer. The position where the free end portion of the stirrer separates from the wall surface is above the detector and inside the container.
