  • Patent number: 10401754
    Abstract: An exposing unit includes a holding member, an abutting pin protruding on both sides in the vertical direction at the rear side of the holding member, a second support portion provided further to the rear side than the holding member, and a movement mechanism that causes the holding member to move between an exposure position and a retracted position. The second support portion has a gap formed where the rear side of the holding member moves in the vertical direction, and this gap restricts movement of the holding member in the left-and-right direction. The holding member that is moved from the retracted position toward the exposure position by the movement mechanism is guided by the gap formed in the second support portion so that the abutting pin abuts a fitting portion.

  • Publication number: 20190179252
    Abstract: An image forming apparatus includes a main assembly, a photosensitive drum, an optical print head, a receiving portion, a portion-to-be-engaged, and a guiding portion. The guiding portion is provided between the portion-to-be-engaged and the receiving portion with an interval from both the portion-to-be-engaged and the receiving portion. The guiding portion guides movement of the cleaning member in a direction from the receiving portion toward the portion-to-be-engaged while limiting movement of the cleaning member in a direction different from the longitudinal direction of the cleaning member to engage the engaging portion with the portion-to-be-engaged.
