<P>PROBLEM TO BE SOLVED: To provide a developing device capable of suppressing shake of a magnet roller and also keeping a developing gap between a photoreceptor and a developing roller constant, and to provide an image forming apparatus including the developing device. <P>SOLUTION: A developing sleeve 49 is supported to be rotatable around an axial line of a shaft 51 of the magnet roller 50, at one end in its axial line direction. A developing gap adjusting member 60 being a bearing member is constituted to be fitted and held in a fitting part 62 formed in an image forming apparatus body 1A along the axial line direction. The developing gap adjusting member 60 has a cylindrical part 70 and a mounting part 71 projecting outward in a radial direction at one-side end of the cylindrical part 70. By decentering an axial center of an outer periphery of the cylindrical part 70 and an axial center of a non-driving-side end 51b of a magnet roller shaft 51, and by angularly displacing the cylindrical part 70 around the axial line of its center, the non-driving-side end 51b of the magnet roller shaft 51 can be positionally displaced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
