Abstract
A transfer apparatus includes a transfer unit, a first detector, a supplying unit, a second detector, and a controller. The transfer unit transfers a toner image onto an object. The first detector detects humidity. The supplying unit supplies, to the transfer unit, a transfer voltage, a setting voltage in a first case, and a setting current in a second case. The second detector detects a current flowing through the transfer unit upon supply of the setting voltage and a voltage across the transfer unit upon supply of the setting current. The controller controls the supplying unit such that, when transfer is performed in the first case, a transfer voltage derived using the setting voltage and the detected current is supplied, and when transfer is performed in the second case, a transfer voltage derived using the setting current and the detected voltage is supplied to the transfer unit.
