ABSTRACT:
An image forming apparatus for forming an image with an electrophotographic process, that includes: a power source; a first drive unit having a capacitative load and driving each part of the apparatus; a second drive unit having a capacitative load and driving each part of the apparatus; and a power supply control circuit that is provided on a power supply path between the power source and the second drive unit, that switches whether or not electric power is supplied to the second drive unit. The power supply control circuit includes: a field-effect transistor with its source connected to the power source side of the power supply path, and its drain connected to the second drive unit side of the power supply path; a first resistive element connected between the field-effect transistor's gate and its source; a second resistive element and a capacitative element that are connected in parallel with the first resistive element, and connected with each other in series between the gate and the source.
