摘要： An image-forming device which facilitates, with a simple structure, the realization of suitable transfer condition control in more situations is disclosed. While the transfer voltage applied to a transfer member such as a transfer roller is detected by a transfer voltage detector, the transfer current is detected by a transfer current detector, and these are transmitted to a CPU. The CPU determines the target current which is to be the control target from the transfer voltage and transfer current, and drives a step-up circuit so as to perform constant current control based on the target current which has been determined. By calculating the target current using calculation formulas which differ by transfer voltage range, suitable transfer condition control under more environments and conditions can be realized.

摘要： A power supply includes a transformer, a second output line, a second output line, a controller, and a current bypass circuit. The transformer has a primary side and a secondary side. The first output line derived from a first point on the secondary side. The first output line outputs a first voltage. The second output line is derived from a second point on the secondary side. The second output line outputs a second voltage lower than the first voltage. The controller controls an amount of current flowing in the primary side based on the second voltage so that the second voltage is maintained at a prescribed voltage. The current bypass circuit controls current flowing in the first output line to flow in the first output line when a potential difference between the second voltage and the second voltage exceeds a prescribed value.
