摘要： An image forming apparatus includes a rotatable photosensitive member, an image forming portion, and a light irradiating portion configured to irradiate the photosensitive member with light after transferring the toner image onto the transfer material. The light irradiating portion includes a first light guide body configured to extend along a rotation axial direction of the photosensitive member, a light source portion provided to face an end surface portion of the first light guide body in the rotation axial direction, a reflecting portion disposed to face the first light guide body in an intersecting direction intersecting with the rotation axial direction, and a second light guide body comprising a facing portion disposed to face the first light guide body and to oppose the reflecting portion through the first light guide body, and configured to irradiate the photosensitive member with the light transmitted through the first light guide body.

摘要： A cleaning unit includes a case, a blade, a swing member, a first coil spring, a second coil spring, and a plurality of first engaging portions. The first coil spring is provided on a first end side of the blade in the longitudinal direction and configured to pull the swinging member. The second coil spring is provided on a second end side of the blade in the longitudinal direction and configured to pull the swinging member. The plurality of first engaging portions are provided on one of the case or the swinging member at the first end side of the blade and configured to selectively engage a one end side of the first coil spring at different positions with respect to the longitudinal direction of the blade so that a contact pressure of the blade against the image bearing member caused by the first coil spring is changed.

摘要： An image forming apparatus includes a rotatable photosensitive member, a charging unit, a developing unit, a support frame, and a sensor unit. The sensor unit is detachably attached to the support frame in a direction that intersects a rotation-axis direction of the photosensitive member and includes a potential sensor, a support portion, a fixing portion, an electric board, and a linking portion. The support portion supports the potential sensor at an area from the charging unit to the developing unit in a rotational direction of the photosensitive member. The fixing portion is fixed to the support frame at a position that faces an area from the developing unit to the charging unit in the rotational direction of the photosensitive member. The support portion is positioned with respect to the support frame at a position downstream of the support portion in an attachment direction of the sensor unit.
