Abstract:
1. An image forming apparatus comprising: an image carrier; a transfer member to form a transfer nip between the transfer member and the image carrier; a power supply to output one of an alternating-current-based voltage including at least an alternating-current voltage and a direct-current voltage to the transfer member so that a toner image on the image carrier is transferred onto a recording medium at the transfer nip; and a power supply controller to cause the power supply to start switching to the alternating-current-based voltage a first time after the power supply stops outputting the direct-current voltage in the case that output of the power supply is switched from the direct-current voltage to the alternating-current-based voltage, and to cause the power supply to start switching to the direct-current voltage a second time after the power supply stops outputting the alternating-current-based voltage in the case that output of the power supply is switched from the alternating-current-based voltage to the direct-current voltage, the second time being longer than the first time.
