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.
