Image forming apparatus including retaining part for retaining movable guide in prescribed position

摘要

An image forming apparatus includes a discharge unit, fixing unit, movable guide, cover, and retaining part. The discharge unit discharges a sheet out of a main body. The fixing unit thermally fixes developer image deposited on the sheet to provide an image-fixed sheet. The movable guide is movable between a first position and second position. The movable guide guides one surface of the sheet in the first position. The movable guide exposes a conveying path in the second position. The cover is movable between an open position where the movable guide is exposed and a closed position where the movable guide is covered. The movable guide is in the first position while the cover moves from the closed position to the open position. The retaining part is configured to retain the movable guide in the second position after the movable guide moves from the first position to the second position.

1. An image forming apparatus comprising:
a main body; a sheet discharge unit configured to discharge a sheet out of the main body; a fixing unit including a heating member to thermally fix developer image deposited on the sheet to provide an image-fixed sheet; and a movable guide disposed near the heating member and defining at least a part of a conveying path for guiding the image-fixed sheet toward the sheet discharge unit, the movable guide being movable about a rotational shaft defining an axial direction and between a first position and a second position, the movable guide being configured to guide one surface of the image-fixed sheet in the first position, and the movable guide being configured to expose the conveying path in the second position; a cover disposed on a top of the main body and configured to move between an open position in which the movable guide is exposed and a closed position in which the movable guide is covered, wherein the movable guide is disposed in the first position while the cover moves from the closed position to the open position; and a retaining part configured to retain the movable guide in the second position after the movable guide moves from the first position to the second position, the retaining part being a protrusion extending in the axial direction, wherein the movable guide has a retained part configured to contact the protrusion in a direction perpendicular to the axial direction, and wherein the movable guide is configured to be disengaged from the protrusion and move from the second position to the first position by receiving pressure from the cover when the cover moves from the open position to the closed position.
