    摘要： In an image forming apparatus, a cover 558 rotates from an open position to a closed position, so that an urging portion 561 urges a first portion-to-be-urged 566, and a slidable portion 525 moves from a rear side toward a front side. By this, an optical print head 105 moves from a retracted position toward an exposure position. Thereafter, when the cover 558 further rotates, the urging portion 561 moves from the first portion-to-be-urged 566 onto a second portion-to-be-urged 567 and moves on the second portion-to-be-urged 567. By this, the slidable portion 525 and link portions 651-654 are kept in a rest state without being moved with rotation of the cover 558.

    摘要： An image forming apparatus includes a drum cartridge including a photosensitive drum, a movable optical print head including a light emitting element and a lens array, and a portion-to-be-contacted. The photosensitive drum and a light emergent surface of the lens array are spaced from each other to permit insertion of a cleaning member therebetween from an outside of the main assembly. The portion-to-be-contacted provided in a main assembly and configured to be contacted by the cleaning member to prevent further insertion of said cleaning member after said cleaning member cleans said light emergent surface by sliding on the light emergent surface from one end side toward the other end side of the light emergent surface with respect to a longitudinal direction of said lens array.

    摘要： There is provided an optical scanning device and an image forming apparatus including the optical scanning device. The optical scanning device includes an optical box containing light source units, a rotating polygon mirror, and a motor. In order to prevent the entire optical box from being deformed by deformation occurring in the installation region due to heat of the driving unit, the optical box includes a connection region between a second sidewall and an installation region where a driving unit is installed. The optical box further includes regions provided next to the connection region and having heights different from each other. A concave portion is formed in the connection region.

    摘要： An optical scanning apparatus includes a light source configured to emit a light beam, a rotating polygon mirror configured to deflect the light beam such that the light beam scans a photosensitive member, an optical box to which the rotating polygon mirror is attached and which includes a first portion, and a holding member configured to hold the light source, including a second portion and a protrusion portion, and attached to the optical box such that the first portion of the optical box and the second portion of the holding member form a gap therebetween, wherein the holding member is attached to the optical box with an adhesive poured into the gap, and the protrusion portion is arranged toward the optical box from the holding member along a position in the gap into which the adhesive is poured to prevent the adhesive from falling off the position.
