摘要： An image forming apparatus includes an image bearer, an exposure device, a drive device, a cleaning body, and an exposure device holder. The exposure device is disposed on a motion trajectory between an exposure position and a retracted position and emits light to the image bearer via a lens having a lens surface at the exposure position. The drive device causes the exposure device to move between the exposure position and the retracted position. The cleaning body disposed on the motion trajectory of the exposure device tilts a cleaning surface when contacting with the lens surface of the exposure device. The exposure device holder supports the exposure device while changing an attitude of the exposure device such that the lens surface remains in contact with the cleaning surface of the cleaning body when the exposure device moves from the retracted position to the exposure position.

摘要： An optical writing unit includes in a housing a light source projecting a light beam, a deflector to deflect the light beam projected from the light source, a focusing lens, and a lens adjusting device. The focusing lens is long in a main scanning direction and focuses the light beam onto a scan target. The lens adjusting device rotates the focusing lens about a substantially center portion thereof as a rotation fulcrum on a plane perpendicular to an optical path of the light beam so as to adjust the position of the light beam illuminating the scan target. The focusing lens has an asymmetric cross-section relative to a center line of the focusing lens in a direction of the optical path in a sub-scanning plane perpendicular to the main scanning direction, and the center of gravity of the focusing lens is offset from the center line toward the rotation fulcrum.

摘要： An optical scanner includes a light source including a plurality of light emitting elements, a polygon mirror which deflects light from the light source for scanning a surface of a subject, an optical element arranged between the light source and the polygon mirror, having optical power in a sub scanning direction, a synchronous detector which detects the light deflected by the polygon mirror for synchronous detection and generates a signal for controlling a timing at which the scanning of the surface is started, and a fixing element which secures one end of the optical element. The light emitting elements of the light source are aligned with a certain tilt angle relative to the sub scanning direction. Light from one of the light emitting elements disposed closest to the fixing element in a main scanning direction is used for synchronous detection.

摘要： An image forming apparatus includes a recording device and an apparatus body to internally house the recording device. The apparatus body includes an attachment unit to be removably mounted in the apparatus body and an apparatus body-side connector. The attachment unit includes an attachment-side connector to be electrically connected to the apparatus body-side connector. The apparatus body also includes a pressing portion to press the attachment unit in a direction in which the attachment-side connector faces the apparatus body-side connector in a state where the attachment unit is attached to the apparatus body. The direction is orthogonal to a mounting direction of the attachment unit. The apparatus body further includes a movable member holding the pressing portion movable between a first position where the pressing portion is closest to the apparatus body-side connector and a second position where the pressing portion is farthest from the apparatus body-side connector.
