PROBLEM TO BE SOLVED: To provide a developing apparatus configured to prevent density unevenness in an output image even when a developer regulation member is drawn to a magnet member and a distance between a developing sleeve and the developer regulation member is reduced, and an image forming apparatus. ! SOLUTION: A developing apparatus 4 includes: a developing sleeve 44 which carries two-component developer including toner and carrier; a magnet roll 44a which is arranged in the developing sleeve 44 to carry the two-component developer on the developing sleeve 44 by means of a magnetic force; and a developer regulation member 42 which is formed of a magnetic material and is fixed at a longitudinal end, to regulate a layer thickness of the developer on the developing sleeve 44. The developing sleeve 44 has a groove 44b formed on a surface. The groove 44b is formed so as to make a developer conveyance force higher as it goes toward a longitudinal center of the developing sleeve 44. ! COPYRIGHT: (C)2015, |
