Abstract
A toner storage apparatus to which a toner cartridge is mountable by being moved in a moving direction includes a toner storage frame that has a reception port and a seal attachment surface, stores toner supplied from the cartridge via the reception port, and has a protrusion from the attachment surface, and a seal portion that is attached to the attachment surface, has a rubbing surface that rubs against the cartridge when the cartridge is moved in the moving direction, and has a communication hole with the reception port. At least part of the protrusion is inside the communication hole and upstream of the reception port in the moving direction. An end of the protrusion is closer to the attachment surface than the rubbing surface in a direction perpendicular to the attachment surface. The seal portion contacts an outer peripheral surface of the protrusion extending in the perpendicular direction.
