Abstract:
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.

Claim (Index 1):
An image forming apparatus having a drum unit rotatably supporting a photosensitive drum, where the lower side of the photosensitive drum is exposed by a plurality of lights from a side lower than a rotational axis of the photosensitive drum in the vertical direction, the image forming apparatus comprising:\n a holding member configured to hold\n a circuit board having a plurality of light-emitting elements configured to emit light to expose the photosensitive drum, and \n a lens configured to collect the light on the surface of the photosensitive drum, \n and configured to reciprocally move between an exposure position where the light-emitting elements expose the photosensitive drum, and a retracted position further retracted from the drum unit than the exposure position; a first moving member configured to support one end side in the longitudinal direction of the holding member in a direction opposite to the gravitational direction, at a side further downstream from the lens and the circuit board in a direction from an other end of the holding member in the longitudinal direction of the holding member toward the one end of the holding member in the longitudinal direction, and to cause the one end side to move in the direction of reciprocal movement by moving in the direction of reciprocal movement while supporting the holding member; a second moving member configured to support the other end side in the longitudinal direction of the holding member in a direction opposite to the gravitational direction, at a side further downstream from the lens and the circuit board in a direction from one end of the holding member in the longitudinal direction toward the other end of the holding member in the longitudinal direction, and to cause the other end side to move in the direction of reciprocal movement by moving in the direction of reciprocal movement while supporting the holding member; a first abutting portion that is provided to the holding member at a side further downstream from the first moving member in a direction from the other end of the holding member in the longitudinal direction toward the one end of the holding member in the longitudinal direction, and that is configured to protrude from the holding member further toward the drum unit side than a light emission face of the lens and abut one end side of the drum unit in the longitudinal direction; and a second abutting portion that is provided to the holding member at a side further downstream from the second moving member in a direction from the one end of the holding member in the longitudinal direction toward the other end of the holding member in the longitudinal direction, and that is configured to protrude from the holding member further toward the drum unit side than a light emission face of the lens and abut another end side of the drum unit in the longitudinal direction, wherein force in the direction opposite to the gravitational direction is applied to a portion between the first moving member and the second moving member, regarding the holding member that has been moved from the retracted position toward the exposure position by the first moving member and the second moving member, with the first abutting portion and second abutting portion abutting the drum unit.
