Abstract
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.
