First Claim
1. An image forming apparatus comprising:
- a photosensitive member which holds an electrostatic latent image;
a developing unit which supplies a liquid developer obtained by dispersing a toner in a carrier liquid to the electrostatic latent image to form a visible image on the photosensitive member;
a transfer member onto which the visible image is transferred;
an image stabilizing unit which applies an electric field to the visible image to enhance adsorption among the toners forming the visible image and between the toners and the photosensitive member;
a drying unit which blows an air current to the visible image having the adsorption to the photosensitive member enhanced by the image stabilizing unit to dry and remove the carrier liquid; and
a shielding member which is disposed between the drying unit and the image stabilizing unit and which inhibits liquid droplets of the carrier liquid flowing backwards toward the image stabilizing unit from the drying unit from reaching the image stabilizing unit.

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.

10. An image forming apparatus using a liquid developer comprising:
-
a photosensitive member which holds an electrostatic latent image;
a developing unit which supplies a liquid developer obtained by dispersing a toner in a carrier liquid to the electrostatic latent image to form a visible image on the photosensitive member;
a transfer member onto which the visible image on the photosensitive member is transferred;
a blowing mechanism which blows an air current having a predetermined speed with respect to the photosensitive member in a region along an outer peripheral surface of the photosensitive member between the developing unit and the transfer member;
an image stabilizing mechanism which applies an electric field to enhance adsorption among the toners constituting the visible image on the photosensitive member and between the toners and the photosensitive member; and
a shielding member which is disposed between the blowing mechanism and the image stabilizing mechanism and which prevents liquid droplets of the carrier liquid flowing backwards toward the image stabilizing mechanism from the blowing mechanism from reaching the image stabilizing mechanism. - View Dependent Claims (11, 12)

13. An image forming method comprising:
-
forming an electrostatic latent image on a photosensitive member;
selectively supplying a liquid developer obtained by dispersing a toner in a carrier liquid to the formed electrostatic latent image to form a visible image on the photosensitive member;
applying an electric field to the visible image formed on the photosensitive member in such a manner that an electrostatic force is exerted on the toner forming the visible image on the side of the photosensitive member;
blowing an air current having a predetermined speed to the carrier liquid remaining together with the visible image on the photosensitive member to remove the carrier liquid; and
recovering scattered droplets generated by the carrier liquids flying/scattering from the surface of the photosensitive member by a recovery member constituted of a porous member which absorbs the droplets.
