    Abstract: A multistage paper feeding/conveying apparatus has a plurality of recording paper storing devices vertically arranged at multiple stages; a paper feeder for feeding a sheet of recording paper one by one from arbitrary one of the recording paper storing devices; and a vertical conveyer vertically extending and opposed to a paper feeding side of each of the recording paper storing devices. The vertical conveyer conveys the sheet of recording paper fed from the paper feeder to a paper receiving section of an image forming apparatus. The paper feeder has a single paper feeding unit which can selectively come in contact with a front end portion of an uppermost sheet of recording paper on an upper face thereof with respect to sheets of recording paper stored within the plural recording paper storing devices. The paper feeding unit and the vertical conveyer have a single endless conveying belt and a device for forming an electric charge pattern for adsorbing the sheet of recording paper to the endless belt. A method for feeding the recording paper is also shown.

    Abstract: A color recording apparatus has an electric charge carrier which is circulatingly movable, an electrostatic latent image forming unit for forming a latent image which corresponds to an original image on the carrier, a development unit for developing the latent image; a transfer unit for transferring the developed image formed on the carrier to a record paper in a transfer process, a conveyor for conveying the record paper forward and backward with respect to the transfer unit, and a control unit which repeats control operations for controlling the latent image forming unit to form a latent image on the carrier, for controlling the development unit to develop the latent image, for controlling the conveyor to convey the record paper forward, for controlling the transfer unit to transfer the developed image to the record paper, and for controlling the conveyor to convey the record paper backward at least for one time. The control unit controls the conveyor prior to the transfer process so that the record paper is positioned at a point which is a predetermined distance before a transfer point and that a forward movement of the record paper is started on the basis of an information signal which is output in response to a state of starting an electrostatic latent image forming operation each time the transfer process is carried out.
