A developing device includes: a housing in which a developer is contained; a cover member configured to cover an upper opening of the housing; a developer holder that is supported by the housing and holds the developer on an outer surface and rotates; and a regulating member that faces the developer holder and is configured to regulate an amount of the developer on the outer surface. The device also includes a first exit path inclined toward an inside of the housing which is configured to exit air from the inside of the housing to an outside of the cover member. A second exit path connects the first exit path and a filter member provided on the cover member, in which the filter member prevents passage of the developer and allows for passage of air.

An image carrier unit, insertable into and removable from an apparatus housing, includes: an image carrier; a protection cover removable from and attachable to the image carrier and including a covering portion and a block, the covering portion covering an exposed portion of the image carrier, the block being disposed on a near side in an insertion-removal direction and protruding in a direction crossing the insertion-removal direction; and a surface opposing a far side of the block in the insertion-removal direction, wherein the block is pressed by a protrusion movable toward the apparatus housing.

A power supply structure includes a bearing, a first spring, and a second spring. The bearing supports a rotary member that axially rotates while contacting with a contact target. While receiving power, the first spring contacts with and presses the bearing with an end portion of the first spring to bring the rotary member into contact with the contact target. The second spring extends from the first spring toward the contact target and contacts with the rotary member.

Power supply structure, charging device, assembly, and image forming apparatus

A charging device includes a charging member that is opposed to and contacts a charged body, the charging member extending axially and rotating in response to rotation of the charged body, a cleaning member that extends axially along the charging member, and contacts a surface of the charging member to clean the charging member, a holding member that holds the charging member and the cleaning member in a manner allowing their displacement by a substantially constant amount while maintaining a distance between their axes, multiple bearing members provided to the holding member with their rotation being arrested, the bearing members individually supporting the shafts of the charging member and cleaning member in a manner allowing their rotation, the bearing members being displaced to follow a change in orientation of the shafts, and an urging member that urges the holding member to press the charging member onto the charged body.

A powder container includes a body and a pair of walls that blocks one longitudinal end of the body and the other longitudinal end of the body. Powder is accommodated within the powder container which is mounted to an apparatus using the powder in a posture where a longitudinal direction of the body is a transverse direction of the apparatus. The powder container has an opening, through which the powder is supplied to the apparatus, formed in a lower position of the body in a posture where the powder container is mounted to the apparatus. The powder container includes a shutter and a shield. The shutter is, prior to mounting the powder container to the apparatus, in a closed location to block the opening and, when the powder container is mounted, is moved along an outer peripheral surface of the body to an opened location to open the opening.
