摘要： A developing agent leakage preventing member is provided that is attached to the developer housing and that has a housing attaching face which contacts with the developer housing, a front side face which opposes the housing attaching face, and two side faces each of which connects to each other end portions of the housing attaching face and the front side face in the longitudinal direction of the opening of the developer housing. At least one of the side faces of the developing agent leakage preventing member is formed as an inclined side face that is inclined in a predetermined direction relative to the housing attaching face when pressed from the front side face side. In a developing apparatus, developing agent (toner) leakage is avoided.

摘要： An image forming apparatus includes: a plurality of development units having developing-agent carriers which are provided in correspondence to three or more developing agents, and developing electrostatic latent images on surfaces of image carriers to form developing-agent images on the image carriers; and a recovery unit that recovers the developing agent adhering to the developing-agent carrier during non-development operation. The recovery unit is provided for at least the development unit other than the development unit that transfers the developing-agent image first in sequence among the plurality of development units. When one of the plurality of development units performs development by the developing agent whose charge capability is higher than that of the developing agent of the development unit that transfers the developing-agent image later in sequence, the recovery unit starts recovery of the developing agent or performs recovery operation for improving recovery capability of the developing agent.

摘要： A layer-thickness regulating member may include a thin plate member and a projection member. The projection member includes a first pressure contact portion that comes into pressure-contact with each of seal areas, a second pressure contact portion that comes into pressure-contact with each of side end areas, and a third pressure contact portion that comes into pressure-contact with a central area. A notched portion is formed at a position of the distal end of the thin plate member where each of the second pressure contact portions is formed, by cutting the thin plate member from an end edge of the distal end toward a downstream side of the rotation direction of the developing agent carrier.

摘要： A developer cartridge includes a developer cartridge case for accommodating a developer, a developing roller, a toner layer thickness control blade, and a side sealing member. The developing roller is supported by the developer cartridge case such that a circumferential surface thereof is exposed to an outside of the developer cartridge case along a width direction. The toner layer thickness control blade includes a blade body portion made of a metallic plate. A tip portion of the blade body portion is disposed at a sliding portion of the developing roller and the side sealing member so as to contact with the side sealing member. A frictional heat generated at the sliding portion is released to the outside of the developer cartridge case through the blade body portion in order restrain a leak of the developer as much as possible.

摘要： A color image forming apparatus may include photoconductors, developing rollers, and cases, each configured to hold developer to be supplied to a corresponding photoconductor from a corresponding developing roller, and each having an elongated opening in which the developing roller is disposed. Also included are a side seal member disposed at each end of the elongated opening in a longitudinal direction of the opening, each side seal member contacting a peripheral surface of the developing roller at each end of an axial direction of the developing roller, and a belt configured to move in a transporting direction parallel to an arrangement direction of the photoconductors, the belt being disposed below the developing rollers. The belt can be disposed to avoid contacting the photoconductors in an area defined by the side seal members being projected onto a plane on a surface of the belt parallel to an axis of the photoconductors.
