摘要： A developing device is capable of preventing developing agent from leaking from a developing frame of a developer cartridge. The developer cartridge includes a developing agent carrying member including a rubber roller, a first seal including a first fluffing member, and a second seal including a second base member and a second fluffing member fixed thereto. The second base member and the second fluffing member have downstream end portions in a rotational direction of the developing agent carrying member. The downstream end portion of the second base member is positioned upstream of the downstream end portion of the second fluffing member. The downstream end portion of the second fluffing member is nipped between the first fluffing member and the rubber roller.

摘要： A cartridge includes a developing roller, supply roller, input rotary body, developing roller rotary body, and supply roller rotary body. The developing roller/supply roller rotary bodies transmit the drive force inputted from the input rotary body to the developing roller/supply roller, respectively. The developing roller rotary body includes first and second drive input parts having different diameters. The input rotary body includes first and second drive output parts engaged with the first and second drive input part, respectively and having different diameters. The first drive output part is movable between a first position and second position. The first drive input part and the first drive output part are engaged when the first drive output part is in the first position. The second drive input part and the second drive output part are engaged when the first drive output part is in the second position.

摘要： The developing device includes a casing, a developing roller, a thickness regulating blade, and a seal member. The developing roller has an outer peripheral surface carrying developer. The thickness regulating blade is configured to regulate a thickness of the developer carried on the outer peripheral surface and has an opposed surface confronting the casing. The thickness regulating blade further has one end part supported on the casing and another end part provided with a press member in sliding contact with the outer peripheral surface. The press member is located on the opposed surface and protrudes toward the developing roller. The press member is formed with a receiving portion depressed inward at its widthwise ends in an axial direction of the developing roller. The seal member is disposed between the thickness regulating blade and the casing and contacting at least a part of the receiving portion.
