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 groove, an exposure device and an adjustment member. In the groove, an end portion of a rotation shaft of a photosensitive drum is inserted. The exposure device is configured to emit a laser light on the photosensitive drum to form an electrostatic latent image. The adjustment member is configured to shift the end portion of the rotation shaft in a direction other than a vertical direction in the groove to adjust a skew of the laser light.
