Image forming apparatus

An image forming apparatus comprising:

• an image forming unit configured to form an image on a sheet;
• a casing accommodating the image forming unit;
• a door configured to be opened and closed with respect to the casing, and configured to be moved to a first opened position and a second opened position, the first opened position being a position where the door is inclined by a first angle with respect to a closed position, where the casing is closed and a sheet conveyance path is formed, to expose the sheet conveyance path, the second opened position being a position where the door is inclined by a second angle that is greater than the first angle with respect to the closed position to expose the sheet conveyance path;
• a connecting member connected to the casing and the door;
• a guide member provided on the door, the guide member including a first guide configured to guide a guided portion of the connecting member in a case that the door is moved between the closed position and the first opened position, and a second guide branched from the first guide and configured to guide the guided portion in a case that the door is moved to the second opened position, wherein the connecting member is configured to retain the door at the first opened position by engagement of the guided portion of the connecting member and an end of the first guide and to retain the door at the second opened position by engagement of the guided portion of the connecting member and an end of the second guide;
• and
• a regulating portion configured to move, in a state where the door is retained at the first opened position by the guided portion of the connecting member engaging the end of the first guide, from a regulating position where the guided portion is regulated from moving from the first guide to the second guide by contact with the regulating portion, to an allowing position where the guided portion is allowed to move from the first guide to the second guide,
• wherein, in a case where the door is opened in a state where the regulating portion is at the regulating position, the guided portion is regulated from moving from the first guide to the second guide by the regulating portion, and
• wherein, in a case where the door is opened in a state where the regulating portion is at the allowing position, the guided portion moves from the first guide to the second guide to allow the door to be at the second opened position.
