Abstract

An apparatus for uniformly supplying the liquid developer and an image forming apparatus having the same are provided. The developer supplying apparatus includes a manifold connected to a connection tube for supplying a liquid developer from an outside and having a developer inlet through which the liquid developer flows into a developing chamber, and a developer dispersion unit, disposed in the developing chamber and located adjacent to an upper part of the developer inlet, for guiding the liquid developer flowing into the developing chamber through the developer inlet so that the liquid developer is dispersed in a horizontal direction. The liquid developer flowing into the lower part of the developing chamber does not directly move toward the upper part of the developing chamber, but is dispersed in a horizontal direction, so that the liquid developer is uniformly dispersed into the whole part of the developing chamber.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a wet electrophotographic printer using a liquid developer. In particular, the present invention relates to an image forming apparatus capable of uniformly supplying a liquid developer into a developing chamber of a developing unit. Background technique [0002] Typically, an image forming apparatus such as a wet electrophotographic printer has a developer supply system. The developer supply system supplies liquid developer to the developing unit to form an image. The developer supply system is classified into an integral type developer supply system or a detachable type developer supply system. In the integral type developer supply system, the developer cartridge is integrally formed with the developing unit. Optionally, in the detachable developer supply system, the developer cartridge is connected to the developing unit through a connecting pipe. [0003] Generally, a detachable...
