PROBLEM TO BE SOLVED: To maintain a distance between a developing rotating body and an image holding body and a distance between the developing rotating body and a layer regulation member with a simple configuration, accurately.SOLUTION: An end support component 8 on a non-driving side of a developing rotating body 5 includes: a first support part 11 which protrudes toward a portion corresponding to a developing portion of an inner peripheral surface of the developing rotating body 5; a second support part 12 which protrudes toward a portion corresponding to a regulation portion facing to a layer regulation member 4 of developer, of the inner peripheral surface of the developing rotating body 5; a pressing part 13 which protrudes toward a portion different from te first and second support parts 11, 12, of the inner peripheral surface of the developing rotating body 5, and presses the first and second support parts 11, 12 against the inner peripheral surface of the developing rotating body 5; and a regulation part 14 which protrudes toward an image holding body 1 so as to regulate a gap between the image holding body 1 and the developing rotating body 5. |
