Abstract
A characteristic measuring portion measures current-voltage characteristics of a primary transfer member before a toner image for a first surface of a sheet is primarily transferred. A characteristic information storage portion stores characteristic information that indicates the current-voltage characteristics. A first transfer voltage determining portion determines a first transfer voltage based on a first target current value and the characteristic information. A second transfer voltage determining portion determines a second transfer voltage based on a second target current value and the characteristic information that was used when the first transfer voltage was determined, the second target current value being smaller than the first target current value. A voltage control portion applies the first and second transfer voltages to the primary transfer member by a constant-voltage method when the toner images for the first and second surfaces of the sheet are primarily transferred, respectively.
