Abstract: A liquid development apparatus uses a developer to develop electrostatic latent images included in a plurality of image portion regions formed successively on an image carrier with an inter-image region being interposed. The liquid development apparatus includes a developer carrier and a control unit. Only a single developer carrier is provided so as to establish one-to-one relation with a single image carrier, it transports the developer to a development position opposed to the image carrier, and it develops the electrostatic latent image while it abuts to the image carrier. The control unit carries out prescribed control such that an amount of the developer supplied from the developer carrier to the inter-image region on the image carrier is reduced or set to zero.
