<P>PROBLEM TO BE SOLVED: To provide a function for measuring a sheet or surroundings thereof, in addition to a basic function of a conveying roller itself, by embedding a wire-less measuring means in the conveying roller. <P>SOLUTION: A pair of conveying rollers 10 are provided with a first roller 11, a second roller 12, a spring member 13, a wire-less pressure sensor 0, or the like embedded in the first roller 11. The pressure sensor 0 measures the pressure to be applied to the sheet 200 when the sheet 200 passes through. A control part 30 sets the image forming condition (transfer temperature, fixing temperature and conveying speed) on the basis of a result of the measurement from the pressure sensor 0 transmitted by radio wave signals. <P>COPYRIGHT: (C)2007,JPO&INPIT |
