Abstract
A developing unit of an image forming apparatus includes a developing member to develop an electrostatic latent image on a photosensitive medium with a developer, a first feed member to feed the developer to the developing member, and a reset member disposed above the developing member to reset the developing member. Accordingly, expenditure for consumables is reduced, because a developer cartridge is separately provided. Additionally, efficient developer agitation is provided. Furthermore, a consistent image quality is achieved, because a plurality of augers move vertically and horizontally to circulate the developer inside the developing unit.
