    摘要： A device for controlling the density of toner of different colors individually stored in a plurality of developing units which are arranged around a photoconductive element senses toner density at a predetermined period which differs from one of the developing units to another. Each of the developing units is associated with a different kind of toner density sensing device.

    摘要： A light absorbing body is located to adjoin the back of an image carrier which is made of a light transmitting member. A latent image representative of an exclusive pattern for density detection is formed in a non-image region of the image carrier and developed by toner of any of multiple colors to become a toner image adapted for density detection. The toner image is illuminated so that image density is detected in terms of the intensity of light which is reflected by the toner image. The light absorbing body is made up of a plurality of absorbing members each having predetermined absorptivity. The absorbing members are selectively used in association with the spectral reflectivity characteristic of toner.

    摘要： An electrophotographic image forming apparatus operable in a monochrome mode and color mode wherein toner images are sequentially formed on an image carrier by toner of a plurality of colors. The toner images of different colors are sequentially transferred to a single transfer member one above the other to complete a color image. In the color mode when toner of two or more colors are to be transferred to the transfer member one above the other, at least one of the color images on the image carrier is discharged before the transfer to the transfer member. In the monochrome mode the image is not discharged before transfer.
