Abstract
An image formation apparatus includes a processing station for forming an image on a recording medium, input device for setting the density of the image formed on the recording medium to a desired value; a controller for controlling the power supplied to the process station in response to the input device setting to form the image of the desired density set by the input device; and a range-shifter for shifting the range of the power controllable by the controller to maintain the density substantially constant.
