A developing device includes: a developer carrying member; a first chamber; a second chamber; a partition wall; a communicating portion; and a feeding member, provided rotatably in the first chamber, for feeding the developer in the first chamber. In a circulation path, the feeding member includes a first region corresponding to a developer coating region of the developer carrying member and a second region, provided downstream of the first region with respect to a feeding direction of the feeding member, corresponding to a region outside the developer coating region of the developer carrying member. Feeding power per unit driving time of the feeding member is set at a smaller value in the first region than in the second region. |
