Image forming apparatus provided with contacting-separating member capable of moving developing roller relative to photosensitive drum

摘要

An image forming apparatus includes: a casing; photosensitive drums juxtaposed with each other in a juxtaposed direction; developing units each including a developing roller; an opening-closing member; and a first contacting-separating member. The opening-closing member is movable between an open position and a closed position. The first contacting-separating member is provided at the opening-closing member and movable relative to the casing in the juxtaposed direction for moving, in a state where the opening-closing member is at the closed position, the developing roller between an adjacent position adjacent to or in contact with the corresponding photosensitive drums and a separated position spaced apart from the corresponding photosensitive drums.

1. An image forming apparatus comprising:
a casing formed with an opening; a photosensitive drum having an axis extending in an axial direction, the axial direction defining a first side and a second side opposite to the first side; a developing unit configured to be mounted in and withdrawn from the casing through the opening in the axial direction, the developing unit including a developing roller; an opening-closing member disposed on the first side of the axial direction and configured to move between an open position for exposing the opening and a closed position for covering the opening; and a first contacting-separating member provided at the opening-closing member and configured to move relative to the casing for moving, in a state where the opening-closing member is at the closed position, the developing roller between an adjacent position adjacent to or in contact with the photosensitive drum and a separated position spaced apart from the photosensitive drum.
