摘要： An electrophotographic apparatus equipped with a photosensitive device rotatable which is responsive to exposure light so as to allow formation of a toner image thereon and an intermediate transfer device rotatable which is brought into contact with the photosensitive device so that the toner image formed on the photosensitive device are transferred onto a surface of the intermediate transfer device. The photosensitive device has a reference mark indicative of a predetermined position in its rotational direction and the intermediate transfer device also has a reference mark representative of a predetermined position in its rotational direction. These reference marks are detected by first and second reference position sensors, thereby measuring the rotational periods of the photosensitive device and the intermediate transfer device so as to calculate a difference therebetween. A control section controls start timings of the formations of the toner images on the photosensitive device on the basis of the calculated period difference as time periods from the time that the first reference position sensor detects the reference mark of the photosensitive device.

摘要： An electrophotographic system for use as a laser beam printer, a copying machine, or the like has an image carrier for receiving an electrostatic latent image, a developing device for developing the electrostatic latent image into a toner image with toner, and a toner hopper for storing into a toner, and a toner hopper for storing the toner. A plurality of toner feeders is disposed in the toner hopper, for supplying the toner from the toner hopper to the developing device. The toner feeders being successively arranged with respect to the developing device such that those toner feeders which are disposed more remotely from the developing device feed progressively smaller amounts of toner. The toner feeders are rotatable to feed the toner to the developing device, and the toner feeders which are disposed more remotely from the developing device rotate at progressively lower speeds or have progressively smaller areas of contact with the toner. Since the amounts of toner fed by the toner feeders are progressively smaller the more remotely disposed from the developing device they are, the amount of toner supplied to a toner feeder is smaller than the amount of toner fed by the toner feeder, which prevents the toner from being aggregated in the toner hopper.
