PROBLEM TO BE SOLVED: To provide a developing device where the generation of an unevenness in image density can be suppressed even when an unevenness is generated in a developer pool. SOLUTION: In the device, a projecting part 13 facing a developing sleeve 4 is provided in a supporting case 11 as a developer quantity deviation decreasing member that decreases the deviation in the quantity of developer on a developing sleeve 4 in an axial direction of the developing sleeve more downstream in a carrying direction of the developer 3 on the developing sleeve 4 than a developing range between the developing sleeve 4 and a photoreceptor drum 1 and in a range that is on the upstream side in a carrying direction from a toner feeding part where toner feeding from a toner hopper 8 is carried out. |
