Abstract

A developing device for use in an electrophotographic image forming apparatus, includes a developing member for developing a latent image formed on an electrophotographic photosensitive member, a developer containing portion for containing a developer to be used in developing with the developing member, the latent image being formed on the electrophotographic photosensitive member, an agitating member for agitating the developer contained in the developer containing portion, and a frame rotatably supporting the agitating member and having a hole for rotatably supporting the agitating member, of which an end enters the hole and is rotatably supported by the hole. The length of the agitating member in contact with the inner surface of the hole is shorter, in the longitudinal direction of the hole, than the length of the agitating member present in the hole.
