Image forming apparatus

An image forming apparatus comprising:

• a main body;
• a process cartridge being detachably mounted to the main body along a direction perpendicular to a rotational axis direction which is a direction of a rotation axis of a photosensitive member, the process cartridge including,
• the photosensitive member, and
• a charger facing a surface of the photosensitive member and charging the surface of the photosensitive member;
• and
• an exposure device that exposes the photosensitive member at a state in which the process cartridge is mounted, the exposure device including,
• a plurality of light emitting devices arranged along the rotational axis direction, and
• a facing part,
• wherein the charger is arranged to be adjacent to the photosensitive member at a downstream side with respect to a mounting direction of the process cartridge,
• wherein the exposure device is positioned on a first line, which intersects with the rotation axis and is perpendicular to the mounting direction when seen from the rotational axis direction, at a state in which the process cartridge is mounted,
• wherein the facing part is a part of the exposure device that is positioned closest to the photosensitive member and faces the surface of the photosensitive member when seen from the rotational axis direction, at a state in which the process cartridge is mounted, and
• wherein the charger is positioned at an opposite side of the exposure device with respect to a second line which is parallel with the mounting direction and passes the facing part when seen from the rotational axis direction.
