摘要： An image forming apparatus includes an optical print head, an optical print head moving mechanism, an abutting portion, a projected portion, an opposing portion, and a preventing portion provided on the projected portion so that in a state in which a drum cartridge is dismounted from a main assembly of the image forming apparatus, the preventing portion is contacted to the opposing portion by movement of the optical print head moved by the moving mechanism toward a side downstream of the exposure position with respect to the movement direction and prevents further movement of the optical print head in the movement direction and so that in a state in which the drum cartridge is mounted in the main assembly and the abutting portion contacts the drum cartridge, the preventing portion is in non-contact with the opposing portion.

摘要： A resin holding member is supported by a one link member and another link member at positions further outside from both ends of a lens array and both ends of a circuit board in a rotational axis direction of a photosensitive drum, but further inside from an abutting pin and another abutting pin. Force in the opposite direction from the gravitational direction is applied to a portion of the holding member between the link members in a state where the abutting pins are abutting a drum unit. Accordingly, warping of the holding member is suppressed.

摘要： 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.
