手段とを具備して成る画像形成装置。 A latent image carrier on which an electrostatic latent image is formed, and a toner in a two-component developer carried on the developer carrier are electrostatically transferred to the electrostatic latent image to form the latent image. a replaceable developing device for visualizing; a means attached to the developing device for replenishing toner into the two-component developer; and a means for replenishing toner into the two-component developer; and a density detection sensor for detecting the density of a reference image visualized by a device and operating the toner replenishing means so that the toner density of the developer is maintained within a certain range. A toner color detection means detects the color of toner in the two-component developer contained in the developing device, and a reference latent detection means detects the color of the toner in the two-component developer contained in the developing device, and a reference latent detection means is provided to detect the toner color in the two-component developer contained in the developing device. An image forming apparatus comprising: a light amount setting means for changing the amount of light irradiated onto a latent image carrier during image formation in accordance with the color of toner detected by the toner color detecting means.
