Abstract
An image density control apparatus which includes a photoreceptor having a photosensitive surface to be uniformly charged to a reference potential and formed with a charge latent image by a reference light amount, a device for developing the charge latent image at a reference developing potential so as to obtain a test pattern, a device for detecting density of the test pattern so as to control image forming condition during an actual image formation according to the detected value. The image density control apparatus further includes a reference condition control device which sets the reference image forming condition for forming the test pattern in accordance with the image forming condition for forming a document which was previously set by detecting a representative density of the document.
