Abstract: A developing device includes a housing, a developing roller, a developer conveying section, and a conveying screw. The developing roller includes a stationary magnet, and a sleeve rotatable around the stationary magnet. The developing roller faces a photoconductive drum. The developer conveying section is disposed below the developing roller for circularly conveying developer therein. The conveying screw conveys developer to supply developer to the developing roller. The stationary magnet includes a separation pole for producing a magnetic field that causes separation of developer from the sleeve. The housing includes a standing wall disposed downstream of the developing position in a rotational direction of the sleeve and facing the developing roller. The standing wall is formed with at least one opening that faces the separation pole in a horizontal direction. The developing device further includes at least one filter section covering the at least one opening.

Abstract: An image forming apparatus includes a main body housing, an image carrier, a developing device, a developer container, and an interference mechanism. The image carrier is stored in the main body housing and has a circumferential surface on which an electrostatic latent image is formed. The developing device is stored detachably in the main body housing and supplies a developer to the electrostatic latent image to develop the electrostatic latent image. The developer container is stored detachably in the main body housing and supplies the developer to the developing device. The interference mechanism disables the developing device from being removed from the main body housing, in a state in which the developer container is mounted to the main body housing.

Abstract: An image forming apparatus includes a transfer belt rotating in a rotational direction, photosensitive drums, primary transferring parts, static eliminating parts and cleaning parts. The static eliminating part is arranged between the primary transferring part and the cleaning part, and includes a light guide body and a light source arranged at one end side of the light guide body. The static eliminating part irradiates upstream and downstream sides from the light guide body in the rotational direction with the static eliminating light. The image forming apparatus comprises a first light shading part and/or a second light shading part. The first/second light shading part is arranged between the photosensitive drum at a downstream/upstream side from the light guide body in the rotational direction and the light guide body to adjust pre-transfer/post-transfer static eliminating light quantity from the light guide body to the downstream/upstream side photosensitive drum.

Abstract: A toner guide member includes a toner discharge port that is located above and faces a toner introduction port of a waste toner container, and the toner guide member forms, in its inside, a passage of waste toner from an end portion of a drum cleaning device to a toner discharge port. A first paddle conveyance member including a plurality of first blade portions rotates in a first rotation direction in the toner guide member. A second paddle conveyance member including a plurality of second blade portions rotates in a second rotation direction that is opposite to the first rotation direction, at a position lower than the first paddle conveyance member. A pivotal trajectory of the plurality of first blade portions partially overlaps with a pivotal trajectory of the plurality of second blade portions.
