Abstract
An image forming apparatus includes an image holding unit, a transfer unit, a first-resistance detection unit, a second-resistance detection unit, and a selection unit. The image holding unit holds an image. The transfer unit includes a transfer member and a counter member. The transfer member is disposed in contact with an image holding surface of the image holding unit. The counter member is disposed across the image holding unit from the transfer member. The counter member is connected to a transfer power supply to cause a transfer electric field to act on a transfer region between the image holding unit and the transfer member. The transfer unit causes the image held by the image holding unit to be electrostatically transferred onto a recording medium transported to the transfer region. The first-resistance detection unit detects system resistance of the counter member, the image holding unit, and the transfer member. The second-resistance detection unit detects system resistance of the counter member alone or system resistance of the counter member and the image holding unit. The selection unit selects the first-resistance detection unit or the second-resistance detection unit, depending on a type of the recording medium.
