Patent attributes
A developing apparatus for an electrophotographic image forming apparatus, the developing apparatus includes a developing means for developing an electrostatic latent image formed on an electrophotographic photosensitive member; a developer accommodating container for accommodating a developer to be used by the developing member; a first stirring member for receiving a driving force from a main assembly of the electrophotographic image forming apparatus to star the developer accommodated in the developer accommodating container; and a second stirring member for stirring the developer accommodated in the developer accommodating container. The second stirring member is rotatable by being contacted by the first stirring member rotated through a predetermined angle when the first stirring member receives the driving force from the main assembly of the apparatus. The first stirring member stirs at least a part of a region of the developer which is stirred by the second stirring member.
