摘要： The invention is to provide an improved high voltage transfer power supply and an image forming apparatus, regardless of resistance connected in series to the transfer roller and impedance change of the transfer roller. The high voltage transfer power supply, if the voltage produced from the output winding NS1 of the transfer transformer T1 is controlled based on the set value of register 8 merely by the process of ATVC, can provide neither an appropriate transfer voltage nor an excellent transfer image. Accordingly, a correction value resulting from the resistance R2 and the impedance change of the transfer roller by means of CPU12, and a set value in a register 8 is corrected by the correction value to obtain an optimal transfer image of the original.
