Wet-type developing apparatus and image forming apparatus using the same

A wet-type developing apparatus in which a latent image carrying member and a squeeze member are moved in the opposite directions to each other without coming into contact with each other and a liquid toner layer on said latent image carrying image member is squeezed between said latent image carrying member and-s aid squeeze member, which comprises:

• a developing roller and a first power source for generating an electric field to form the liquid toner layer on said latent image carrying member so that said liquid toner layer in advance of said squeeze member has a thickness smaller than the gap between the latent image carrying member and said squeeze member, said developing roller rotating in an opposite direction to a movement direction of said latent image carrying member;
• said developing roller rotating in said opposite direction to said movement direction of said latent image carrying member and application of said electric field generated by said first power source making said liquid toner layer penetrate into the gap together with said latent image carrying member;
• and
• a second power source for forming an electric field between said squeeze member and said latent image carrying member,
• wherein said liquid toner layer penetrating into the gap between said squeeze member and said latent image carrying member is brought into contact with said squeeze member by an electric attractive force of the electric field generated by said second power source to thereby form a desired meniscus.
