Abstract:
A holding member that holds an optical print head for exposing a photosensitive drum is provided with one abutting pin at each end thereof in the longitudinal direction. Each abutting pin has both a function of forming a gap between the optical print head and the photosensitive drum, and a function of restricting movement of the holding member in the X direction and Y direction. The holding member is supported by a link member further toward the side of the photosensitive drum than the lower end portion of the abutting pins.

Claim (Index 11):
An image forming apparatus having a drum unit rotatably supporting a photosensitive drum, the image forming apparatus comprising:\n an optical print head configured to expose the photosensitive drum; a movement mechanism configured to reciprocally move the optical print head between an exposure position where the photosensitive drum is exposed, and a retracted position that is further retracted from the drum unit than the exposure position; a first abutting pin that is formed protruding from one end side of the optical print head in the longitudinal direction of the optical print head toward the drum unit side and the opposite side from the drum unit side, and that is configured to be abutted against a first abutted portion formed on one end side of the drum unit in the longitudinal direction to position the one end side of the optical print head in the longitudinal direction as to the drum unit; a second abutting pin that is formed protruding from an other end side of the optical print head in the longitudinal direction toward the drum unit side and the opposite side from the drum unit side, and that is configured to be abutted against a second abutted portion formed on the other end side of the drum unit in the longitudinal direction to position the other end side of the optical print head in the longitudinal direction as to the drum unit; and a facing portion that is provided facing both sides of the second abutting pin in the vertical direction, at the opposite side of the side to which the drum unit is disposed as to the optical print head, and that is configured to come into contact with the second abutting pin in the vertical direction, to restrict movement of the second abutting pin in a perpendicular direction perpendicular to both the longitudinal direction and the direction of reciprocal movement, wherein the movement mechanism includes\n a first moving member that supports the optical print head from the opposite side from the side where the drum unit is disposed as to the optical print head, at a position further toward the drum unit side than, out of both ends of the first abutting pin in the direction of reciprocating movement, the end portion at the opposite side from the drum unit side, and reciprocally moves the optical print head, and \n a second moving member that supports the optical print head from the opposite side from the side where the drum unit is disposed as to the optical print head, at a position further toward the drum unit side than, out of both ends of the second abutting pin in the direction of reciprocating movement, the end portion at the opposite side from the drum unit side, and reciprocally moves the optical print head.
