Abstract
In a wet-type image forming apparatus, a plurality of patch images are successively transferred to a recording medium corresponding to a plurality of transfer biases obtained as bias value of the transfer bias is changed; density detecting unit measures image density of each of the plurality of patch images on the recording medium and detects a range of bias values of transfer bias in which the image density of patch image is substantially saturated; and the bias value of transfer bias when a normal image is formed on the recording medium is set to be within the range of bias values of transfer bias in which the image density of patch image is substantially saturated and to be not larger than absolute value of the bias value at which the image density of patch image is substantially saturated.
