Abstract
A liquid electrophotographic image forming apparatus using an ink developing solution having a high concentration where a non-volatile carrier is used as a dispersion solvent includes a photosensitive body, a charge unit increasing a potential of the photosensitive body to a charge potential, an exposure unit projecting a beam onto the photosensitive body and forming a latent electrostatic image, a developing solution supply unit supplying a developing solution to the photosensitive body, the developing solution having a high concentration where a non-volatile carrier is used as a dispersion solvent, a developing unit receiving the developing solution having the high concentration to form a developing film having the high concentration and to develop the latent electrostatic image, a transfer unit contacting the photosensitive body and moving the developed image to a recording medium, and a fixing unit fixing the transferred image in the recording medium at a temperature lower than a flash point of the non-volatile carrier. By using the non-volatile developing solution having the high concentration, a smell generating due to vapor of a carrier can be prevented, and an image forming…
