Summary:PROBLEM TO BE SOLVED: To provide an image forming device and an image forming method capable of realizing the optimum performance without degrading the printing throughput of the image forming device by detecting presence/absence of paper sheets in a cassette at the shortest timing. SOLUTION: The distance L1 shorter than the distance L from a paper sheet rear end to the position 11 at which a detection flag 3a is detached is determined when it is assumed that the paper sheet is completely rigid from a tip 10 of the paper sheet waiting position waiting in a cassette 8 by referring to the characteristic of the actual paper sheet (mass, rigidity and environmental atmosphere). By the distance L1, the shortest timing at which presence/absence of the succeeding paper sheets in the cassette can be determined. Based on this timing, the supply of succeeding paper sheets is started to effectively improve the printing throughput. COPYRIGHT: (C)2007,JPO&INPIT
