ABSTRACT:
A two-component developer unit of an electrophotographic image forming apparatus includes a developer rectifier having a lifting guide portion and a developer collection guide portion. The lifting guide portion guides a developer agitated by an agitating unit upward along a circumferential direction of a developer magnet roller. The developer collection guide portion keeps the developer to move down to the lifting guide portion between a developer blade and the lifting guide portion. A non-uniformity of image intensity can be solved without giving an overweight load to the developer and a photoreceptor and without increasing a driving torque of the developer and the photoreceptor.
