Electrophotographic image forming apparatus and cartridge

A cartridge comprising:

• a photosensitive member;
• a charging member capable of charging the photosensitive member;
• a first unit including the photosensitive member and the charging member;
• a developing member for depositing toner onto the photosensitive member;
• a second unit including the developing member and movable between a developing position in which the toner is capable of being deposited onto the photosensitive member from the developing member and a spaced position in which at least a part of the developing member is spaced from the photosensitive member;
• a contact force receiving portion for receiving a contact force for moving the second unit to the developing position when the second unit is in the spaced position;
• and
• a spacing force receiving portion for receiving a spacing force for moving the second unit to the spaced position when the second unit is in the developing position,
• wherein, as viewed along a direction of a rotational axis of the developing member when the second unit is in the spaced position, the cartridge is divided into a first section and a second section by a line that (i) is tangential to a surface of the photosensitive member at a side of the photosensitive member that is opposite to a side of the photosensitive member that is adjacent to the charging roller and (ii) intersects a line that extends through a rotational axis of the photosensitive member and a rotational axis of the charging roller, with the rotational axis of the photosensitive member and the rotational axis of the charging roller being in the first section and the contact force receiving portion and the spacing force receiving portion being in the second section,
• wherein, when the second unit is in the spaced position, a space is capable of being formed between the contact force receiving portion and the spacing force receiving portion, and
• wherein, as seen in a direction along a rotational axis of the developing member in a state that the space between the contact force receiving portion and the spacing force receiving portion is formed, the contact force receiving portion disposed at a position closer to the rotational axis of the photosensitive member than the spacing force receiving portion is to the rotational axis of the photosensitive member.
