Multiple-output power supply unit including voltage generation circuits for applying voltages to loads and image forming apparatus having the power supply unit

摘要

A multiple-output power supply unit includes: a first voltage generation circuit that generates a first voltage applied to a first load; a first output terminal that outputs a second voltage corresponding to the first voltage to a second load; a first constant voltage element that is connected to the first output terminal; a second constant voltage element that is provided between the first constant voltage element and a ground; and a second output terminal that is connected between the first constant voltage element and the second constant voltage element so as to output a third voltage having a predetermined potential difference from the second voltage to a third load that is provided in a state of being electrically connected to the second load.
