ABSTRACT:
An image forming apparatus includes several image forming units which are vertically arranged, paper connecting units which connect the paper discharging section of one image forming unit and the paper feeding section of another image forming unit where the two units are vertically adjacent, and a paper separating mechanism to switch the employed paper conveying path from one path to another. Such a structure requires floor space only as much as that required for one image forming unit, and yet provides various functions, e.g. double-sided printing, mulitple copying on one side of a paper with different originials, high-speed printing, multi-colored printing, printed side up discharging, printed side down discharging, job stocking, and sorting. The invention results in a compact and inexpensive image forming apparatus with various high quality fuctions.
