Abstract: An electronic-component attachment structure includes an electronic component and a support member. The electronic component has a connection electrode exposed on a surface of a substrate. The support member supports the substrate of the electronic component in abutment with an attachment surface so as to allow the connection electrode to be externally connectable. The support member has a positioning supporter that elastically deforms by being relatively joined to a positioning portion provided in the substrate and that positions and supports the substrate to the attachment surface with restoring force generated as a result of the elastic deformation.

Abstract: A developing device includes a developer holding body, a container, a contact member, and a restriction member. The developer holding body supplies a developer to an image holding body. The container accommodates the developer holding body and is formed with an opening portion facing the image holding body. The deformable contact member is fixed in the container and on a downstream side of the opening portion body in a rotation direction of the developer holding body and includes a tip end which extends toward an inner side of the container and which contacts with the developer holding body. The restriction member is disposed on an image holding body side of the contact member and restricts the tip end of the contact member from deforming so as to be in a state where the contact member is directed toward an outer side of the container.

Abstract: A spacing device includes a spacing member that spaces first and second rotating bodies having first and second shaft portions, respectively, apart from each other. The spacing member is provided on the second shaft portion and includes a supporting portion that supports the first rotating body; and an opening through which the second shaft portion extends and including an idling portion that allows a hook part of the second shaft portion to rotate idle, and a catching portion that catches the hook part. The first and second rotating bodies are spaced apart when the hook part is in the catching portion and the first rotating body is supported by the supporting portion. The first and second rotating bodies are allowed to rotate when the spacing member rotates until the supporting portion is oriented downward in a direction of gravitational force and the hook part moves to the idling portion.

Abstract: A developing device includes a housing that includes an accommodating portion, a development opening portion, a developing roller, and a supply receiving portion; an opening/closing member; a guiding portion; and an elastic pushing member. The opening/closing member includes a body, a guide portion, and an extended protrusion, the body having a cutaway end portion, the guide portion being provided at left and right end portions of the body except where the cutaway end portion exists, the extended protrusion being formed by causing at least a portion of an end portion of the body to extend and protrude in an opening direction. The housing is provided with a sandwiching holding portion that holds at least a portion of the extended protrusion of the opening/closing member by sandwiching at least the portion of the extended protrusion by the sandwiching holding portion and the supply receiving portion.

Abstract: An imaging unit includes a support body; a photoconductor supported by the support body; a developing device supported by the support body to swing about a pivot arranged at a pivot portion, and including a development roller having a gap holding member that contacts a portion of the photoconductor; and a driven coupling member provided at a first end portion of the development roller, and removably coupled to a driving coupling member to which a rotational power is transmitted. The pivot portion is arranged so that the developing device swings toward the photoconductor by self weight. The driving or driven coupling member has at least three protruding portions that restrict rotation of the developing device when the members are coupled. The development roller rotates in a generation direction of an action that causes the developing device to swing toward the photoconductor when receives the rotational power and is rotationally driven.

Abstract: 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.
