Patent ID: 8787784

Claim:
An image forming apparatus comprising: an image carrier configured to carry a toner image obtained by developing an electrostatic latent image using toner; a transfer unit configured to transfer the toner image from the image carrier onto a recording medium; an applying unit configured to apply a voltage to the transfer unit; a detector configured to detect a current being made to flow in the transfer unit; an acquisition unit configured to acquire the image density of the toner image to be transferred in the transfer unit; and an adjusting unit configured to adjust a voltage to be applied to the applying unit on the basis of a change in the relationship between the current detected by the detector at the timing of transferring the image corresponding to the image density acquired by the acquisition unit to the recording medium and the image density acquired by the acquisition unit, wherein the detector is configured to detect the current being made to flow in the transfer unit when a toner image having a predetermined image density is being transferred in the transfer unit, and wherein the adjusting unit is configured to adjust the voltage to be applied to the applying unit on the basis of a change in the current detected by the detector.
