Abstract: A development device includes a developer container, a developer bearing member, a mixing/transporting member, an opening/closing member, and a drive mechanism. The developer container contains a developer. The developer bearing member is rotatably supported by the developer container. The developer bearing member also has a surface facing an image bearing member on which an electrostatic latent image is to be formed. The developer is borne on the surface of the developer bearing member. The mixing/transporting member mixes and transports the developer in the developer container. The opening/closing member opens and closes a developer outlet for discharging an excess of the developer in the developer container. The drive mechanism drives the opening/closing member in association with driving of the developer bearing member or the mixing/transporting member to open the developer outlet.

Abstract: A film member in a development device can vibrate with respect to an internal wall in the development device. An idler gear in the development device includes a projection and is reciprocally movable between a first position and a second position. The first position is a position where the projection is apart from an end edge of the film member in response to a rotation of a toner supply roller when image formation is performed. The second position is a position where the projection overlaps with the end edge of the film member in response to a reverse rotation of the toner supply roller when image formation is not performed. The projection causes the film member to vibrate by intermittently coming into contact with the end edge of the film member along with a rotation of the idler gear at the second position.

Abstract: An image forming apparatus includes a shield case in which a circuit board mounted with an electric circuit is contained. The shield case has an electrical conductive case main body and an electrical conductive lid member. The case main body has an aperture formed in a part of one face. The lid member has one end turnably supported by the case main body and the other end fastened to the case main body by a screw when the aperture is closed. The case main body and lid member have an engaged part and an engaging part engaged with each other when the aperture is closed. The engaging part is formed so as to clamp the engaged part. The shield case is configured so that contact force between the engaging part and engaged part is increased, if the screw is rotated in a fastening direction when the aperture is closed.
