Image forming apparatus

An image forming apparatus comprising:

• an apparatus body having a body contact;
• and
• a cartridge detachably mountable to the apparatus body, the cartridge including a first unit having a photosensitive drum and a second unit having a developing roller for supplying toner to the photosensitive drum, and an electrical contact brought into contact with the body contact, the first unit and the second unit moving about a pivot axis between a contact position at which the photosensitive drum and the developing roller come into contact with each other and a spaced-apart position where the photosensitive drum and the developing roller are spaced apart from each other;
• wherein, when viewed in a direction of the pivot axis,
• in a case where a downstream-side end of the electrical contact is a first end and an upstream-side end of the electrical contact is a second end in a rotation direction about the pivot axis in a case where the second unit moves from the spaced-apart position to the contact position,
• the body contact comes into contact with a region of the electrical contact between the first end and a midpoint of the first end and the second end in a case where the second unit is at the contact position, and
• the body contact maintains contact with the electrical contact while the second unit moves between the spaced-apart position and the contact position, and
• wherein in a case where a distance between the first end and the pivot axis is D1, a distance between the second end and the pivot axis is D2, and a distance between the midpoint and the pivot axis is Dc,
• Dc≤D1 and Dc≤D2 are satisfied.
