PURPOSE:To reduce the power consumption of a flash lamp and make the fixation state of a toner uniform to obtain a good image, by providing a conduit- shaped mirror at the rear of the flash lamp and providing a recessed and curved transfer paper passage in the front of the flash lamp. CONSTITUTION:A mirror which is located around an axis X of a flash lamp 1 as the center and has a semicircular section is provided along the axis X at the rear of the flash lamp 1, and a transfer paper passage P consisting of a semicircular part 31 locating around the axis X as the center and vertical parts 32 and 32' extending vertically from both ends of the semicircular part 31 is provided in front of the flash lamp 1. Sucking holes 4 are formed in the transfer paper passage P. A transfer paper is brought closely into contact with the transfer paper passage P by suction and is guided and is fed out from the vertical part 32' through the semicircular part 31. A toner of the transfer paper is fixed with the flash at every length of a fixation region in the semicircular part 31. The length between the transfer paper and the lamp 1 is constant in any position, to make uniform the fixation state of the toner. |
