Abstract
PURPOSE:To smoothly supply the developer by using a material of the same electrification polarity as that of the developer as an inner wall material of a developer storage part and a wall face material of a bottom part of a developing part and setting the lower edge of an opening in the rear of the developing part to the upper part than the uppermost of a developer supply member. CONSTITUTION:When a wall surface of a bottom part 9a of a developing part, an inner wall material of a developer storage part 5 and a developer 4 are set to the same electrification polarity, an accumulation of the developer 4 in a gap between the bottom part 9a and a developer supply member 3, and a coagulation of the developer due to a frictional electrification against the inner wall of a storage part 5 are prevented. Also, the lower edge 8 of a communicating opening 11 of the developing part 9 and the storage part 5 is set to the upper part than the uppermost part 6h of the supply member 3, so that the developer 4 can be carried out easily by a rotation of a developing feeding-out member 6. Moreover, the upper edge 8a of the opening 11 is placed at the supply member 3 side from the lower edge 8 and by providing a blade 7 for making theta=5-45 deg. against the horizontal direction (m), when it is brought closest to the lower edge 8 on the tip of the feeding-out member 6, the developer is supplied more smoothly.
