ABSTRACT:
A device and method for controlling a transfer voltage in an electrophotographic recording apparatus for printing by the page. In the transfer voltage controlling device, a high voltage generator generates a transfer voltage, an exposer starts and stops an exposure in response to a first exposure signal and a second exposure signal, respectively, a transfer roller transfers an image by high pressure with the transfer voltage received from the high voltage generator, and an engine controller generates the first exposure signal for starting an exposure for one page and the second exposure signal for terminating the exposure for the page, and causes the high voltage generator to supply or stop the transfer voltage to the transfer roller upon generation of the first exposure signal or the second exposure signal, respectively.
