An image forming apparatus comprising:

• a cartridge;
• and
• an apparatus body to which the cartridge is detachably mounted in a first direction,
• wherein the cartridge includes:
• a pressing portion provided on an end surface in a second direction intersecting the first direction and a gravity direction;
• a recessed portion provided in the end surface and recessed more than the pressing portion;
• a powered member;
• and
• an electrical contact for receiving power to be supplied to the powered member,
• wherein the apparatus body includes:
• a frame body having a mounting region where the cartridge is mounted;
• and
• a contact unit provided in an end of the frame body in the second direction, the contact unit including a contact and a protrusion protruding toward the mounting region, the contact and the protrusion being movable in the second direction and in a direction away from the mounting region against an elastic force, and
• the contact unit is located at:
• a first position in a non-mounted state in which the cartridge is not mounted to the apparatus body;
• a second position in a mounted state in which the cartridge is mounted to the apparatus body and is in the mounting region of the frame body, the second position being farther away from the mounting region than the first position in the second direction by the protrusion being inserted into the recessed portion and the contact contacting with the electrical contact;
• and
• a third position in a middle state of transitioning of the cartridge from the non-mounted state to the mounted state, the third position being farther away from the mounting region than the second position in the second direction by the protrusion being pressed by the pressing portion of the cartridge so that the contact does not contact with the cartridge.
