摘要：
In an electrophotographic printer, a power supply is connected to a transfer roller to which a current is supplied at a time that a print paper is inserted between a photosensitive drum 10 and the transfer roller. Since respective print papers have different resistances from one another, a voltage according to the kind of the print paper is generated at the transfer roller at a time that a preset current is supplied to the transfer roller, and is held. A sensor is arranged for detecting the width of the print paper, and detects the width of the print paper inserted between the photosensitive drum and the transfer roller. The value of the preset current supplied to the transfer roller 14 is changed so as to adapt to the width of the print paper.
