PURPOSE:To miniaturize a device by simplifying the constitution of a developing part. CONSTITUTION:In a developing tank 18, a guide plate 168, rotary brush rollers 38 and 170 and a pair of rollers 54 are disposed in the carrying direction of a PS plate 12 from an upstream side, and the rotary brush rollers 38 and 170 and a pair of rollers 54 are driven to be rotated. A guide roller 36 is arranged at the upper part of the downstream side end part of the guide plate 168 and backup rollers 34A, 34B, 40A and 40B are arranged to be faced to the rollers 38 and 170. The tip of the PS plate 12 inserted in the tank 18 is guided along the guide plate 168 and inserted between the rollers 38 and 34A from the back end parts of the guide roller 36 and the guide plate 168. At this time, the guide roller 36 is brought into contact with the intermediate part in the carrying direction of the PS plate 12 and the tip of the PS plate 12 passed through the roller 34A is pushed up so as to approach the roller 38. |
