An electrophotographic recording apparatus records an image on a recording paper, either a cut recording sheet or a continuous recording paper, through steps of feeding the recording paper along a paper feed plane exclusively for the recording paper, stopping the recording paper upon the arrival of the same at a predetermined, exclusive starting position, forming an electrostatic latent image on a photoconductor by an exposure unit as the photoconductor is rotated at a fixed surface speed, developing the electrostatic latent image in a toner image by a developing unit by applying a toner charged in a polarity opposite that of the electrostatic latent image, restarting the feed of the recording paper at a feed seed corresponding to the surface speed of the photoconductor upon the arrival of the first line of the toner image formed on the surface of the photoconductor at a position which will coincide with a fixed recording position on the recording paper at a transfer position, transferring the toner image from the photoconductor to the recording paper, and fixing the transferred toner image to the recording paper by a fixing unit. When the toner image is thus formed on the continuous recording paper, a portion of the continuous recording paper carrying the toner image is cut off by a cutting unit, and then the continuous recording paper is retracted to the starting position.
In an electrophotographic recording apparatus having a first paper feed mechanism for feeding cut recording sheets, a second paper feed mechanism for feeding a continuous recording paper, and an electrophotographic recording system which includes a photosensitive member on which a toner image is formed, a transfer unit for transferring the toner image formed on the photosensitive member to the cut recording sheet or the continuous recording paper at a transfer position, and fixing unit for fixing the transferred toner image to the cut recording sheet or the continuous recording paper, the apparatus having a first region defined upstream of the transfer position and a second region defined between the transfer position and a position near the fixing unit, the first paper feed mechanism feeding the cut sheets through the first region in a first feed plane and feeding the cut sheets in the second region in a second feed plane, the improvement wherein the second paper feed mechanism feeds the continuous recording paper through the first and second regions, and wherein the second paper feed mechanism includes a tractor mechanism comprising
