Wet-type developing device and wet-type image forming apparatus

摘要

The present wet-type developing device includes: a developer carrier for carrying a wet-type developer, which contains a charged toner particle and carrier liquid, and supplying the wet-type developer to an image carrier on which an electrostatic latent image is formed; a charge neutralizing unit for neutralizing a charge of the toner particle contained in the wet-type developer remaining on the developer carrier after supplying the wet-type developer to the image carrier; a dispersing unit for dispersing the toner particle in the carrier liquid by acting on the toner particle contained in the wet-type developer neutralized in charge by the charge neutralizing unit; and a removing unit for removing, from the developer carrier, the wet-type developer containing the toner particle dispersed by the dispersing unit.

1. A wet-type developing device comprising:
a developer carrier for carrying a wet-type developer, which contains a charged toner particle and carrier liquid, and supplying said wet-type developer to an image carrier on which an electrostatic latent image is formed; a charge neutralizing unit for neutralizing a charge of said toner particle contained in said wet-type developer remaining on said developer carrier after supplying said wet-type developer to said image carrier; a dispersing unit for dispersing said toner particle in said carrier liquid by acting on said toner particle contained in said wet-type developer neutralized in charge by said charge neutralizing unit; a removing unit for removing, from said developer carrier, said wet-type developer containing said toner particle dispersed by said dispersing unit; a surface potential measuring unit, disposed at a downstream side relative to said dispersing unit and an upstream side relative to said removing unit in a rotation direction of said developer carrier, for measuring a surface potential on said developer carrier; and a control unit for controlling an amount of charge neutralized by said charge neutralizing unit, wherein said control unit controls the amount of charge neutralized by said charge neutralizing unit based on the surface potential on said developer carrier measured by said surface potential measuring unit.
