摘要： A developing apparatus includes a housing; a developing roller; a seal member, and a layer thickness regulating member that contacts a circumferential surface of the developing roller via developer and regulates a thickness of a developer layer on the circumferential surface of the developing roller. The seal member has a sliding contact portion made of fiber having elasticity and sliding-contacting the circumferential surface of the developing roller. The layer thickness regulating member has one end portion that is supported by the housing and the other end portion to which a bent portion is formed to face the seal member, and the bent portion is configured to enter the sliding contact portion.

摘要： An image forming device has a main casing and a cartridge accommodating portion in which a combined unit of first and second cartridges can be loaded. The first cartridge includes a pressing member movable between a first position in which the second cartridge is removed from the first cartridge and a second position in which the second cartridge is combined with the first cartridge. A moving member supported on the main casing is movable between a third position in which the combined unit is unloaded from the main casing and a fourth position in which the combined unit is loaded in the main casing. The pressing member disposed in the second position presses the moving member to move to the fourth position. A determination unit does not start image forming operations until a position detector provided on the main casing detects that the moving member is in the fourth position.

摘要： A developing device includes: a frame having an opening; a developer carrying member rotatably supported to the frame; and a side seal. The developer carrying member is rotatable about its axis in a rotating direction and has an axial end portion in an axial direction. The side seal is disposed between the frame and a peripheral surface of the axial end portion, and has a contact member contacting the peripheral surface. The contact member includes: a first seal member disposed adjacent to an edge of the opening in the axial direction; and a second seal member disposed adjacent to and upstream of the first seal member in the rotating direction. The first seal member permits developer to move inward in the axial direction and provides a mobility of developer therein higher than that of the second seal member that is made of a material that restricts movement of developer.
