ABSTRACT:
An electrophotographic has a transfer belt, a plurality of image-bearing bodies, and a plurality of transferring devices. The transfer belt is driven to run with a print medium placed thereon. The plurality of image-bearing bodies are disposed in a direction in which the transfer belt runs. Each of the plurality of transferring devices opposes a corresponding one of the plurality of image bearing bodies to form a transfer section. Each of the transferring devices selectively receives a first voltage (i.e., transfer voltage Va) and a second voltage (i.e., non-transfer voltage Vb) same as or lower than the first voltage. The first voltage is received when an image of a corresponding color is being transferred from a corresponding one of the image bearing bodies to the print medium. The second voltage is received when the image of the corresponding color is not being transferred from the corresponding one of the image bearing bodies to the print medium.
