The disclosure shows a cleaning blade for electrophotographic equipment, the cleaning blade through which both high hardness and low warping are obtained and excellent toner scraping properties are realized. The cleaning blade (10) includes a blade part (12) comprising a cured material of a urethane composition containing a polyol, an isocyanate, and a crosslinker or a chain extender. The content of the isocyanate is 28.0 mass % or more with respect to the entire composition. The crosslinker or the chain extender comprises a triol having a molecular weight of 150 or less. The content of the crosslinker or the chain extender is 4.0 mass % or less with respect to the entire composition. The content of the triol having a molecular weight of 150 or less is 0.8 mass % or more with respect to the entire composition.

A contact point end portion of a second ring connected to a first ring portion on a power reception portion side protrudes further in the direction of a power reception portion than a contact point end portion of the first ring connected to a spring portion on a power reception portion side.

A structure includes a rotatable rotating member, a blade, a support member, and a frame body. The blade extends in an axial direction of the rotating member and is in contact with or disposed close to a surface of the rotating member. The support member supports the blade such that one end side of the blade projects toward the rotating member in a lateral direction that intersects the axial direction. The frame body is formed by insert molding in which resin is injected while the support member is secured to a mold. The frame body clamps part of the support member so as to support the support member.

A replaceable imaging basket for an electrophotographic image forming device according to one embodiment includes a frame having a positioning slot that is open at a top of the frame for receiving a replaceable unit. An electrical connector is positioned on an inner side of the frame adjacent to the positioning slot. The electrical connector includes an electrical contact on a front of the electrical connector that faces the positioning slot. The electrical connector includes a pair of outer guides and a pair of inner guides on opposite sides of the electrical contact. The inner guides are spaced inward from the outer guides. A top portion of a front surface of each of the outer guides tapers rearward away from the positioning slot as they extend upward. A top portion of a rear surface of each of the inner guides tapers forward toward the positioning slot as they extend upward.

A disassemblable imaging apparatus includes a photo sensing assembly, a toner cartridge, and at least one torsion spring. The photo sensing assembly includes a casing and a photosensitive drum. The casing has an accommodating space. The photosensitive drum is installed on the casing and located at a side of the accommodating space. The toner cartridge is detachably located in the accommodating space. The at least one torsion spring is located in the accommodating space. A part of the at least one torsion spring is installed on the casing, and another part of the at least one torsion spring presses a side of the toner cartridge facing away from the photosensitive drum for pushing the toner cartridge toward the photosensitive drum.

A disassemblable imaging apparatus includes a photo sensing assembly and a toner cartridge. The photo sensing assembly has an accommodating space, a photosensitive side and a fastening side. The photosensitive side and the fastening side are respectively located at two sides of the accommodating space, which are opposite to each other. The toner cartridge includes a main body and a handle. The handle is swingably connected to a side of the main body in order to move an end of the handle, which is away from the main body, close to or away from the main body. The toner cartridge is detachably installed in the accommodating space, and the handle is detachably fastened to the fastening side of the photo sensing assembly.

A transport member, that transports a developer by rotating in a rotation direction that is predetermined around a rotation axis, includes: a shaft part including the rotation axis; and a blade part spirally provided on an outer peripheral surface of the shaft part, wherein the blade part includes a transport surface that is a surface facing a downstream side in a transport direction of the developer along the rotation axis, and a non-transport surface that is a surface other than the transport surface, and the transport member further includes a fin protruding from the non-transport surface of the blade part, the fin being provided with an interval from the outer peripheral surface of the shaft part.

A flange member includes a first cylindrical portion, a second cylindrical portion disposed inside the first cylindrical portion coaxially with the first cylindrical portion, an inwardly protruding portion protruding from an inner circumference of the second cylindrical portion, a first wall extending in the central axis direction and connecting the first cylindrical portion and the second cylindrical portion together and is in contact with a shaft member between the first wall and the second wall to receive a driving force, a second wall opposed to the first wall, and a connecting portion connecting the first cylindrical portion and the second cylindrical portion and connecting the first wall and the second wall. A groove is provided inside the first cylindrical portion and outside the second cylindrical portion. The connecting portion is disposed adjacent to the inwardly protruding portion with respect to the shaft member in the central axis direction.

A replaceable unit for an electrophotographic image forming device according to one embodiment includes a pocket formed on a first side of a housing. A bottom end of the pocket is open for receiving an electrical connector during insertion of the replaceable unit into the image forming device. An electrical contact is positioned within the pocket and is electrically connected to processing circuitry on the housing. An outer guide is positioned on the first side of the housing and below the pocket. A portion of the outer guide inclines inward toward the first side of the housing as the outer guide extends upward. An inner guide is positioned within the pocket on a first inner surface of the pocket, which faces toward the first side of the housing. A portion of the inner guide inclines inward toward the first side of the housing as the inner guide extends upward.
