摘要： A toner transport screw that is capable of maintaining a smooth and stable transport function. The toner transport screw, in which a helical blade is disposed on the circumference of a rotating shaft, has at least one spiral direction reversal part formed by connecting the respective ends of a first blade part and a second blade part, the directions of spiral of the first blade part and the second blade part being in opposite directions. A passage, which allows the toner to pass through the blades in the circumferential direction of the rotating shaft, is formed in the spiral direction reversal part.

摘要： A developing device includes a main body that is arranged between a pair of supporting members and includes a developing roller. Both end portions of the developing roller are supported by the supporting members in a first direction in which the developing roller is movable toward and away from an image carrier. A groove is formed on each of the supporting members. Either one of an end portion of the developing roller and a bearing that supports the end portion is inserted into the groove. Either one of at least one of the end portions of the developing roller and at least one of the bearings is movable in the groove in a second direction that intersects the first direction.

摘要： A cleaning device includes a casing including an opening facing the rotary member, a cleaning member disposed at the opening to contact the rotary member to remove a substance adhering thereto, an entrance seal disposed at the opening to prevent leakage of the removed substance through a gap between the opening and the rotary member, a pair of lateral end seals respectively disposed both end portions of the cleaning member as well as the entrance seal in an axial direction of the rotary member, and a compressing member. A first face of each lateral end seal is attached to the casing. The compressing member compresses each lateral end seal by pressing a second face thereof opposite the first face-and presses a third face of the lateral end seal against the casing in a direction in which the lateral end seal is expanded by the compression.

摘要： A development device includes a developer carrier, a bearing member, a biasing member, and a guide. The developer carrier supplies a developer to an electrostatic latent image formed on an image carrier to develop the electrostatic latent image into a toner image. The bearing member rotatably supports the developer carrier axially. The biasing member is provided on a side of the bearing member opposite the image carrier to apply a force to the bearing member to move the bearing member and the developer carrier toward the image carrier. The guide is disposed about the bearing member to enable the bearing member to move therebetween and guide the bearing member toward the image carrier. The bearing member includes a rotatable part to rotate and slide over the guide while contacting the guide.
