Abstract
Image density control apparatus including a photosensor for detecting a density of an image of an original, and a microcomputer for controlling a light intensity of a light source of a development bias voltage. The microcomputer has a CPU for determining a control output in response to a detection signal from the photosensor and in response to signals from a ROM corresponding to respective positions on the image of the original.
