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 4):
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 sliding portion configured to move by sliding in the longitudinal direction of the holding member; a first spring that is provided to the holding member 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 toward the one end of the holding member in the longitudinal direction, and is configured to impart biasing force to the holding member to bias the holding member in a direction opposite to the gravitational direction; a second spring that is provided to the holding member at a side further downstream from the lens and the circuit board 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 is configured to impart biasing force to the holding member to bias the holding member in the direction opposite to the gravitational direction; a first link portion of which one end side is in contact with the first spring and the other end side is pivotably connected to one end side of the sliding portion in the longitudinal direction, and that is configured to pivot in conjunction with sliding movement of the sliding portion and to deform the first spring in conjunction with the pivoting; a second link portion of which one end side is in contact with the second spring and the other end side is pivotably connected to the other end side of the sliding portion in the longitudinal direction, and that is configured to pivot in conjunction with sliding movement of the sliding portion and to deform the second spring in conjunction with the pivoting; a first abutting portion that is provided to the holding member at a side further downstream from the first link portion 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 link portion 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 spring and the second spring, regarding the holding member that has been moved from the retracted position toward the exposure position in conjunction with the first moving member and the second moving member pivoting, with the first abutting portion and second abutting portion abutting the drum unit.
