Patent number: 6253051Abstract: A wet-type image forming apparatus which allows excess solvent to be effectively removed from the developed image is disclosed. A developing roller develops a latent image on the photoconductor member using the liquid developer composed of toner particles and a solvent. A squeezing roller squeezes excess solvent from a surface of a photoconductor member. A heater heats liquid developer existing on the photoconductor member to a temperature at which the solvent of the liquid developer is prone to vaporize. The heater is provided in one of the developing roller, the squeezing roller, and the liquid developer reservoir.Type: GrantFiled: January 18, 2000Date of Patent: June 26, 2001Assignee: NEC CorporationInventors: Kazuaki Iikura, Takeshi Hirano
