摘要： In an electrophotographic sheet-fed front/back printing machine which is capable of duplex printing and which can be installed in a reduced space, sheets of paper fed from a sheet supply are fed out by a sheet transport conveyer onto an impression cylinder of an electrophotographic printing section in which each of the sheets are printed on one side. The sheets printed on one side are turned over from front to back by a sheet turnover transport unit and are allowed to fall and be supplied onto the sheet transport conveyer. The sheets are each fed again onto the impression cylinder and printed on the remaining other side. Sheets printed on both sides are transported by a printed-sheet transport unit to a print output receptacle in which they are received.
