Abstract:
A wet-type developing device and a wet-type image forming apparatus each employ a developer including a carrier liquid and toner particles dispersed in the carrier liquid. A charging unit is applied with positive voltage. A neutralizing unit is applied with negative voltage. The charging unit and the neutralizing unit are made different from each other in one of a sectional configuration and a length to a developer carrier such that an absolute value of a voltage-current characteristic of the neutralizing unit becomes smaller than an absolute value of a voltage-current characteristic of the neutralizing unit including a constituent element equal to a constituent element of the charging unit.
