摘要： A sheet processing apparatus (100) includes: a first conveying member pair (2; R3, R4) that folds a sheet; a second conveying member pair (3, R6; R6a, R6b) that conveys downstream the sheet folded by the first conveying member pair (2; R3, R4); and a third conveying member pair (4; R3, R5) that further folds the sheet folded by the first conveying member pair (2; R3, R4). The second conveying member pair (3, R6; R6a, R6b) is rotatable forward and reversely when driven to convey, and is locked in one rotational direction but is rotatable in the other rotational direction when not driven.

摘要： In a developing device of the present invention, in a developing zone where an image carrier and a developer carrier face each other, the developer carrier carrying a developer thereon moves at a linear velocity of 150 mm/sec or above, but below 500 mm/sec. The amount of the developer conveyed to the developing zone by the developer carrier is between 65 mg/cm 2 and 95 mg/cm 2 . A magnetic flux generated on the developer carrier in the developing zone by a magnetic pole has a flux density having an attenuation ratio of 40 % in the direction normal to the developer carrier. The flux density in the direction normal to the developer carrier, as measured on the surface, is between 100 mT and 200 mT. Magnetic grains, which constitute the developer together with toner grains, have a saturation magnetization value of 40 x 10 -7 x 4π Wb·m/kg or above, but below 50 x 10 -7 x 4π Wb·m/kg.

摘要： A development device (20) includes a developer bearer (22) to carry the developer to a development range, a magnetic field generator (23) disposed inside the developer bearer (22) for generating magnetic force, a developer regulator (25) for adjusting an amount of the developer, a developer supply compartment (27) disposed adjacent to the developer bearer (22), separated by a side wall (43) from a portion where the developer bearer (22) is provided, a developer agitator (32) provided in the supply compartment (27), and a blocker (44) disposed above the side wall (43) of the supply compartment (27) across a supply gap through which the developer moves from the supply compartment. The magnetic field generator (23) has an attraction magnetic pole and a regulation magnetic pole. The blocker (44) prevents the developer blocked by the developer regulator (25) from moving along a magnetic force line of the regulation magnetic force toward the circumferential surface of the developer bearer (22).

摘要： A toner replenishing device includes a sub hopper (48) (toner container), a toner detection sensor (72), an agitator (74), and a paddle (75). The sub hopper (48) contains toner. The toner detection sensor (72) is located on a wall surface in the sub hopper (48) and detects whether toner remains at a height at which it is located. The agitator (74) rotates in the sub hopper (48) to clean the detection surface of the toner detection sensor (72). The paddle (75) serves as a toner collecting unit that collects toner to the vicinity of the detection surface of the toner detection sensor (72) in the sub hopper.
