Image forming apparatus

An image forming apparatus comprising:

• an apparatus main body including an electrical board, a main body electrical contact electrically connected to the electrical board, and a main body guide portion;
• a cartridge including a developing roller and a memory, the memory including a memory electrical contact;
• and
• a moving unit configured to move into and out of the apparatus main body in a first direction, the moving unit including
• a photosensitive drum,
• a frame rotatably supporting the photosensitive drum and the cartridge is attachable to and detachable from the frame,
• an intermediate electrical contact configured to be in electrical contact with the memory electrical contact of the cartridge,
• a unit electrical contact configured to be in electrical contact with the main body electrical contact,
• a line conductor configured to connect the intermediate electrical contact and the unit electrical contact, and
• a portion-to-be-guided configured to be guided by the main body guide portion of the apparatus main body,
• wherein the portion-to-be-guided is located on an end surface of the frame of the moving unit in a second direction, the second direction being a direction intersecting both the first direction and a vertical direction, the portion-to-be-guided being configured to be guided by the main body guide portion of the apparatus main body while the moving unit is attached to and detached from the apparatus main body, the portion-to-be-guided including a first protrusion and a second protrusion, the first protrusion and the second protrusion protruding in the second direction from the end surface of the frame and extending in the first direction, the first protrusion being supported from under the first protrusion by the main body guide portion of the apparatus main body, the second protrusion being located above the first protrusion and facing the first protrusion, and
• wherein at least part of the line conductor is located in a recess formed by the first protrusion, the second protrusion, and the end surface, the at least part of the line conductor extending in the first direction.
