<P>PROBLEM TO BE SOLVED: To provide a transfer device that improves rate of image transfer to concave portions of a concave and convex surface of a sheet, transfers toner uniformly even to a sheet having a surface with a large degree of concave and convex, and outputs quality images stably irrespective of change in environment or difference in types of sheets. <P>SOLUTION: Transfer voltage is applied from a power source 110 to a counter member 73 in such a way that an electric field is formed by a DC component in a direction where toner on an image carrier 50 is transferred to a transferred body P. Current value of the DC component output from the power source is detected by an ammeter integrated in the power source 110, and the output voltage of the power source 110 is controlled in such a way that the current value of the DC component is made to be a current value set in advance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
