Image forming apparatus

An image forming apparatus to which a cartridge that stores developer is removably attachable, the image forming apparatus comprising:

• a photosensitive member;
• an exposure device that irradiates a surface of the photosensitive member with light to form an electrostatic latent image on the surface;
• a rotary that is rotatable and includes
• a storage unit configured to store the developer supplied from the cartridge, and
• a developing member that forms a developer image on the photosensitive member using the developer stored in the storage unit;
• a moving device that moves the cartridge between an attachment position at which the cartridge is positioned inside the rotary and a displaced position at which the cartridge is positioned outside the rotary;
• and
• an intermediate transfer unit to which the developer image on the photosensitive member is transferred,
• wherein, when viewed in a vertical direction, the intermediate transfer unit, a portion of the rotary, and the exposure device overlap, and
• wherein, when viewed in a displacement direction in which the cartridge moves from the attachment position to the displaced position, the intermediate transfer unit, the exposure device, and the portion of the rotary overlap.
