摘要： A developing device includes a developer carrier which carries a developer, a developing unit housing which rotatably supports the developer carrier, a side seal member which comes into slidable contact with both ends of the developer carrier, a sheet-like elongated seal member which extends in the axial direction of the developer carrier so as to come into slidable contact with the developer carrier, a side seal attachment surface which is formed in the developing unit housing and to which the side seal member is attached, and a support portion which is formed in the developing unit housing and protrudes toward the developer carrier from the side seal attachment surface to support the elongated seal member. The elongated seal member is attached onto the support portion in a state where both ends thereof overlap the side seal member and are opposite the side seal attachment surface. A filler is filled in a gap surrounded by the elongated seal member, the side seal member, the support portion, and the side seal attachment surface. A protrusion for suppressing the spread of the filler is formed at the side seal attachment surface at a predetermined interval from the support portion.

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 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.
