    摘要： A developing unit develops a latent image on an image carrier with toner. A toner cartridge is detachably arranged in parallel with the developing unit, and supplies the toner to the developing unit. An opening is disposed between the developing unit and the toner cartridge, through which the toner passes. The toner cartridge includes a space forming unit that forms a space in the toner stored in the toner cartridge. The space allows the toner to flow into from the developing unit.
