Developer cartridge for a wet-type image forming apparatus

A test apparatus to evaluate the electrical properties of a liquid toner in which a printing quality of the liquid toner may be predicted by evaluating the electrical properties of the liquid toner without performing printing. The test apparatus to evaluate the electrical properties of a liquid toner includes a roller, a conductive flat panel positioned below the roller to move a predetermined distance in contact with the roller, a power supply device applying a voltage to the roller and the conductive flat panel, and a voltage tester provided at the rear of the roller to move together with the roller, testing a voltage of the liquid toner arranged on the conductive flat panel.
