Claim Text:
1. A wet-type developing device that employs a developer including a carrier liquid and a toner particle dispersed in the carrier liquid, the wet-type developing device comprising: a developer carrier configured to develop an electrostatic latent image; a charging unit configured to charge said developer on said developer carrier by discharge; a neutralizing unit configured to neutralize electric charge of said developer after the development by discharge which is equal in manner to the discharge by said charging unit; and a cleaning member configured to remove said developer after the neutralization from said developer carrier, wherein said charging unit is applied with positive voltage, said neutralizing unit is applied with negative voltage, and said charging unit and said neutralizing unit are made different from each other in one of a sectional configuration and a length to said developer carrier such that an absolute value of a voltage-current characteristic of said neutralizing unit becomes smaller than an absolute value of a voltage-current characteristic of said neutralizing unit including a constituent element equal to a constituent element of said charging unit, the voltage-current characteristic indicating a relation between an applied voltage and a current flowing into the developer carrier.
