ABSTRACT:
An electrophotographic apparatus using a liquid developer of the present invention includes a photosensitive member which holds an electrostatic latent image, a plurality of developing unit which supply liquid developers including toner particles and carrier liquid to the photosensitive member to form a visible image, a visible image stabilizing unit which enhances adsorption among toners constituting the visible image on the photosensitive member and between the toners and the photosensitive member by an electric field, a drying unit which dries the visible image formed on the photosensitive member, a periphery of the visible image, or the carrier liquids included in the visible image by an air current, and a shielding unit which is disposed between the drying unit and the visible image stabilizing unit and which prevents deposits attached to the photosensitive member surface together with liquid droplets of the carrier liquid existing on the photosensitive member surface from reaching the visible image stabilizing mechanism.
