Image forming apparatus having improved accessibility to internal units

An image forming apparatus for forming an image on a recording medium, the image forming apparatus comprising:

• a discharge tray configured to support the recording medium, wherein the recording medium is a recording medium on which the image has been formed and which has been discharged to an outside of an apparatus main body of the image forming apparatus;
• an internal unit disposed inside the apparatus main body;
• a door configured to be opened and closed by rotating around an axis to expose and cover a fixing member that removeably attaches the discharge tray to the image forming apparatus;
• and
• a cartridge for being attached to and detached from the apparatus main body,
• wherein opening of the door allows the cartridge to be attached to and detached from the apparatus main body,
• wherein the discharge tray and the door are part of outer surface members of the apparatus main body of the image forming apparatus,
• wherein, by rotating the door to open the door, the fixing member is exposed to the outside of the apparatus main body and is accessible to be detached from the apparatus main body, and
• wherein detaching of the fixing member from the apparatus main body and then detaching the discharge tray from the apparatus main body allows the internal unit to be accessed without detaching the outer surface members of the apparatus main body other than the discharge tray.

An image forming apparatus for forming an image on a recording medium, the image forming apparatus comprising:

• a discharge tray unit having a first side wall, a second side wall, and a discharge tray removeably attached to the first side wall and the second side wall by a fixing member as a surface of the discharge tray unit that is for stacking, outside of the image forming apparatus, the recording medium on which the image has been formed;
• an internal unit having electronics and removeably disposed inside the apparatus main body at a position below the discharge tray;
• and
• a door configured to be opened and closed by rotating around an axis to expose and cover the fixing member that removeably attaches the discharge tray to the first side wall and the second side wall,
• wherein the discharge tray and the door are part of outer surface members of an apparatus main body of the image forming apparatus, and
• wherein, by rotating the door to open the door, the fixing member becomes accessible to be detached, and, by detaching the fixing member and then detaching the discharge tray from the first and second side walls such that the first and second side walls remain attached to the apparatus main body, the internal unit can be detached from the apparatus main body and brought out through an opening exposed by detaching the discharge tray from the apparatus main body, without detaching the remaining outer surface members other than the discharge tray.
