Abstract
An image forming apparatus is usable with a process cartridge which includes an image bearing member; a developer bearing member which develops an electrostatic latent image with developer; an accommodating chamber which contains the developer; and a memory. The image forming apparatus includes a detector for emitting light to a patch of a developer image and detecting reflected light; and a controller for performing image density control when controlling image density to form the developer image, based on a value of image data and information on the reflected light. The memory stores information corresponding to a developer amount in the accommodating chamber, and the controller changes the patch pattern between cases where the information in the memory is information relating to a first amount and a second amount.
