Abstract:
1. An image forming device comprising: a main casing; a first retaining member that retains a plurality of photosensitive drums juxtaposedly arrayed and spaced away from each other in a prescribed direction, the first retaining member configured to move in the prescribed direction between a mounted position in which the first retaining member is mounted in the main casing and a pulled-out position in which the first retaining unit is pulled out of the main casing; a second retaining member that retains a plurality of developing units each opposing a corresponding photosensitive drum and is configured to move between a second adjacent position, in which the plurality of developing units is located adjacent to the plurality of photosensitive drums, and a second retracted position, in which the plurality of developing units is moved away from the plurality of photosensitive drums; an endless belt disposed above the first retaining member to oppose the plurality of photosensitive drums; a plurality of exposure units disposed below the endless belt and configured to move between a first adjacent position, in which each of the plurality of exposure units is located adjacent to the corresponding photosensitive drum to expose thereof, and a first retracted position, in which each of the plurality of exposure units is moved away from the corresponding photosensitive drum in a direction intersecting with the prescribed direction, wherein the plurality of exposure units is provided on the second retaining member; and a tray disposed in confrontation with the first retaining member from below and configured to be inserted into or removed from the main casing, a space being formed by removing the tray from the main casing, wherein the space is occupied by the tray when the tray is inserted in the main casing, the tray configured to hold a medium, wherein each of the plurality of exposure units is configured to move to the first retracted position by moving to the space formed by removing the tray from the main casing, and wherein, when the plurality of exposure units is in the first retracted position, the plurality of exposure units do not interfere with the first retaining member in the prescribed direction when the first retaining member moves from the mounted position to the pulled-out position.
