PROBLEM TO BE SOLVED: To provide a pressure developing means by which abnormal noise and damage caused due to the mutual interference of pressure rollers are eliminated and an image can be formed on the whole surface of a photosensitive and pressure-sensitive recording medium in a short time. SOLUTION: The leading edge part 1a and the trailing edge part 1b of the photosensitive and pressure-sensitive recording medium 1 are detected by a detection means 40. Then, the thick part 39 of endless belts 30 and 31 is controlled so as to be passed between both pressure rollers 21 and 22 simultaneously with the edge parts 1a and 1b of the medium 1. Besides, when the middle part of the medium 1 is pressure-developed by the rollers 30 and 31, the belts 30 and 31 is controlled to be driven so that the flat part 38 thereof is passed between the rollers 21 and 22. |
