Problems solved by technology

In addition, if the developer is under pressure, the internal and external additives forming the developer may be separated, or its shape may be deformed
Further, if an image is formed on a printing medium by a deformed developer, developing characteristics and melting characteristics deteriorate, thereby deteriorating printing quality

Abstract

An image forming apparatus that forms image data on a printing medium, the apparatus including: a developing cartridge having a developer transfer body that transfers a developer to an image receptor, and separately storing the developer that has been transferred and adjusted to A developer storage unit that stores the transferred conditioning developer in the transfer body and the non-transferred developer that is not transferred to the developer transfer body, and the used developer that is separated from the image receptor surface. with a developer storage unit; a print information storage unit storing cartridge print information of a developing cartridge; and a controller calculating an average print density based on the cartridge print information, and if the calculated average print density is lower than a reference print density, controlling the The developing cartridge is described so that the transferred amount of the transferred developer of the developer storage unit to the used developer storage unit can exceed the reference amount.

Description

technical field [0001] Apparatuses and methods consistent with the general concept of the present invention relate to image forming apparatuses, and more particularly, to image forming apparatuses capable of controlling developer consumption according to average printing density and image forming methods thereof. Background technique [0002] Generally, an image forming device forms image data stored in a host device on a printing medium according to a printing signal. The image forming apparatus is configured with: an image receptor, in which an electrostatic latent image is formed; a developer transfer body, which selectively diffuses a developer onto the image receptor (photoreceptor); The developed developer is transferred onto the printing medium to print a desired image on the printing medium. The image forming apparatus described above may be embodied as a printer, a copier, a scanner, and a multifunction printer including these apparatuses. [0003] A detachable de...
