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.

摘要： A sheet conveying device includes a separator to separate a sheet from sheets. The separator includes a separation conveyor; a separation resistance member to press against the separation conveyor via the sheet; a resistance-member holder; a biasing member to contact and bias the resistance-member holder to press the separation resistance member toward the separation conveyor, the resistance-member holder to rotate about a resistance-member rotary shaft to separate from the biasing member in detaching from an apparatus body; and a biasing-member holder configured to rotate about a biasing-member rotary shaft to more incline the biasing member in a state, in which the biasing member is spaced apart from the resistance-member holder, in a moving direction of the resistance-member holder to detach from the apparatus body than the biasing member in a biasing state in which the biasing member biases the resistance-member holder in contact with the resistance-member holder.

摘要： In a light beam scanning device, a plurality of light sources, which irradiates a plurality of light beams in a first direction and is retained by a holder, are disposed at distance from one another in a second direction orthogonal to the first direction. The plurality of light beams are incident, via a coupling optical system, to deflecting and reflecting surfaces of a deflector from a direction that is tilted with respect to a plane orthogonal to the rotational shaft of the deflector. The holder is supported by a housing of the light beam scanning device at a plurality of different positions in a third direction extending from the light source to the coupling optical system.

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.
