Abstract
An image forming apparatus in which a photosensitive sheet and an image receiving sheet are pressed together while being transported by a pressure developing device, the image receiving sheet being then separated from the photosensitive sheet by a separation roller. The pressure developing device continues to transport the photosensitive sheet after the image receiving sheet is separated therefrom, and the transportation of the photosensitive sheet by the pressure developing device is stopped when the trailing edge of the image receiving sheet has passed the separation roller.
Claims5
A sheet transport device for an image forming apparatus, comprising:
- a pressure developing device for transporting a photosensitive sheet coated with light and pressure sensitive microcapsules containing photohardening materials and coloring dyes and an image receiving sheet coated with developer that reacts with the coloring dyes to develop colors, the two sheets superimposed one on top of the other for transportation, during which the two sheets are pressed together to form an image on the image receiving sheet;
- a separating means for separating the image receiving sheet that has passed the pressure developing device from the photosensitive sheet;
- an image receiving sheet sensor for detecting that the trailing edge of the image receiving sheet fed to the pressure developing device and to be separated from the photosensitive sheet by the separating means has passed a prescribed position;
- and
- a control means for performing control on the basis of the detection result of the image receiving sheet sensor so that the transportation of the photosensitive sheet is continued until the trailing edge of the image receiving sheet passes the separating means after passing the pressure developing device.
