Abstract
A wet-type image forming apparatus includes a density detection unit and a charge amount control unit for controlling the charge amount of toner on a liquid developer carrier. An image forming unit forms patch images while the charge amount control unit successively changes the charge amount of toner on the liquid developer carrier in a state in which a development bias is held at a prescribed value. The density detection unit detects the image density of each patch image thereby detecting a range of the charge amount of toner in which the image density of the patch image is almost saturated. The charge amount of toner in normal image formation is set to be equal to or greater than the range of the charge amount of toner in which the image density of the patch image is almost saturated.
