A developing device for developing a latent image formed on an image carrier with a developing liquid containing a carrier liquid and a developing substance, including a developing roller including a roller portion and rotatable while carrying the developing liquid on the roller portion, and a voltage applying device configured to apply a voltage to the roller portion to thereby form an electric field for development between the roller portion and the image carrier, whereby the developing liquid deposited on the roller portion is transferred to a latent image formed on the image carrier. The roller portion has a volume resistivity ranging from 0 Omegacm to 10<7 >Omegacm.
