Image forming apparatus including photosensitive drum and exposing member movable between exposure position close to drum and separated position separated from the drum

摘要

An image forming apparatus includes: a main apparatus body; an opening/closing member; a drum unit including a photosensitive drum and can be pulled out of an accommodating space along an axial direction of the photosensitive drum; an exposing member provided in the main apparatus body and movable between an exposure position and an evacuation position; and a movable mechanism including: a first movable member movable in accordance with an opening/closing operation of the opening/closing member; and a second movable member for moving the exposing member between the exposure position and the evacuation position in accordance with movement of the first movable member. The second movable member supports both end portions of the exposing member. The second movable member moves the exposing member to the exposure position or the evacuation position by the movement of the first movable member in accordance with the movement of the opening/closing member.

主权项

1. An image forming apparatus comprising:
a main apparatus body having an accommodating space partitioned therein and an opening connecting the accommodating space and an outside; a drum unit comprising a photosensitive drum configured to carry a developer image and accommodated in the accommodating space; an opening/closing member configured to rotate between an open position for opening the opening and a closed position for closing the opening, a rotation axis of the opening/closing member extending in a first direction perpendicular to an axial direction of the photosensitive drum; an exposing member extending in a second direction parallel to the axial direction of the photosensitive drum and configured to expose the photosensitive drum to form a latent image thereon; and a movable mechanism comprising: a first movable member configured to contact the opening/closing member and move in accordance with an opening/closing operation of the opening/closing member; a second movable member configured to move the exposing member between an exposure position close to the photosensitive drum and a separated position separated from the photosensitive drum, the exposing member in the separated position being closer to the first movable member than the exposing member in the exposure position; and a restricting member including link members which restrict the exposing member from being moved in the axial direction of the photosensitive drum when the exposing member moves between the separated position and the exposure position, wherein the second movable member is configured to move the exposing member from the exposure position to the separated position by moving the first movable member in accordance with movement of the opening/closing member from the closed position to the open position, wherein the second movable member is configured to move the exposing member from the separated position to the exposure position by moving the first movable member in accordance with the movement of the opening/closing member from the open position to the closed position, wherein the first movable member is configured to slide along the axial direction of the photosensitive drum in accordance with an opening/closing operation of the opening/closing member.
