Apparatus for forming and developing latent electrostatic images with liquid developer and release agent

A wet-type image formation apparatus comprising:

• a latent electrostatic image formation means for forming, on a latent-electrostatic-image-bearable photoconductive member, a latent electrostatic image corresponding to an original image;
• a wet-type development means for developing said latent electrostatic image into a visible toner image with a liquid developer which comprises (a) a carrier liquid comprising a first silicone oil with a siloxane structure and (b) toner particles comprising a coloring agent and a binder resin, which are dispersed in said carrier liquid;
• an image-transfer means for transferring said visible toner image from said photoconductive member to a transfer sheet;
• and
• an image-fixing means for fixing said visible toner image to said transfer sheet, which comprises a heat-application roller, the surface of which is coated with a release agent comprising a second silicone oil with a siloxane structure,
• wherein the viscosity of said first silicone oil used as said carrier liquid for said liquid developer is lower than that of said second silicone oil used as said release agent for said heat-application roller.
