PROBLEM TO BE SOLVED: To provide a magnet roller not demagnetized at a low temperature, capable of preventing an image quality from being fogged and generating irregular density capable of providing a high image quality, and suitable for coloration despite the fact that a magnet piece formed of such an inexpensive magnet material as to have an operating point at the bent point of a demagnetizing curve or below for example, at the temperature of -40 deg.C in a lower right quadrant. SOLUTION: In this magnet roller formed by sticking a plurality of magnet pieces to each other, the magnet pieces not magnetized are stuck on a magnet body shaft, and the magnet pieces and the shaft are magnetized in a stuck state. Then, the other magnet piece is stuck on the magnet piece having the shaft to form a magnet roller. |
