PROBLEM TO BE SOLVED: To solve the problem that throughput is lowered more than necessary in the view of the reduction of warming at a part through which no paper passes since throughput in the case of using a paper of 150 mm length, e.g. with which warming at the part through which no paper passes is small is not different from that in the case of a paper of 249 length with which warming at the part through which no paper passes is large, because there is only one step of the distinction level of small sizes and the sizes are sorted only to a normal size not shorter than 250 mm and a small size shorter than 250 mm. SOLUTION: There are at least two steps of paper feeding intervals corresponding to a material to be heated shorter than a prescribed length, and a relation between the paper feeding interval I1 of the shortest material to be heated and the paper feeding interval I2 of a material to be heated which is longer than this by one step is I1<I2. |
