PURPOSE:To prevent the leakage of gaseous ammonia and improve the workability for the jam or the like, by fastening tips of a soft seal member and a guide plate by a fastening member having a channel-shaped section. CONSTITUTION:The tip of the photosensitive paper exit side of a soft seal member 7 and the tip of a guide plate 9 are fastened by arms 12a and 12b of a fastening member 12 having a channel-shaped section. Consequently, even if the seal member 7 is deformed by heating due to the heat of a heater 4, waving phenomena are not generated to prevent the leakage of gaseous ammonia because the lower arm 12a of the fastening member 12 is adhered to the seal member 7. When the guide plate 9 is is turned to the outside for the jam, the seal member 7 is turned together, and it is unnecessary to position the member 7 again to improve the workability. |
