    摘要： A development device (113) including a developer container (121), a developer bearer (132), a magnetic field generator (133), a developer agitator (118a) to supply the developer to the developer bearer (132), and a developer regulator (116) to adjust a layer thickness of the developer carried on the developer bearer (132). Multiple oval recesses (139) oblique to the axial direction of the developer bearer (132) are formed in the outer circumferential surface of the developer bearer (132) and arranged in a circumferential direction and the axial direction thereof. An upstream inner wall (139a) of the recess (139) in the rotational direction of the developer bearer (132) applies a force to the developer as the developer bearer (132) rotates, and an angle between a long axis of the recess (139) and the axial direction is set so that the force applied by the upstream inner wall (139a) of the recess (139) has a component in a direction substantially identical to the developer conveyance direction of the developer agitator (118a).

    摘要： A development device (113) includes a developer container (117), a developer carrier (132), exposed partly from a casing (125), facing a latent image carrier (108) in a development area (131), a magnetic fields generator (133) inside the developer carrier, having multiple magnetic poles including a developer conveyance pole (P2,P3) to convey the developer downstream from the development area to a developer release portion (137), a developer agitator (118), and a developer regulator (116). A predetermined gap is kept between an outer surface of the developer carrier and an inner wall of the casing downstream from an opening (125a) of the casing, upstream from a developer release portion, in a direction in which the developer carrier rotates. Multiple recesses (139) are formed in the outer surface of the developer carrier at a pitch in a circumferential direction shorter than half a width of a magnetic flux density of the developer conveyance pole in a direction perpendicular to an axial direction of the developer carrier.
