ABSTRACT:
A power supply control subsystem for an image forming apparatus is provided to control the operating timing of multiple DC loads according to selected image forming modes. Electric power is supplied from a single DC power source to a plurality of DC loads through corresponding switching devices inserted therebetween. A control circuit staggers the on-timings of the switching devices so that electric power is supplied to the DC loads in a sequentially, predetermined priority order according to a selected image forming mode.
