    Abstract: A charged particle generating method in which mode is changeable between an ion generation mode and an electron generation mode. In the ion generation mode, a raw material is supplied to a tip end of a charged particle generating electrode through a raw-material passage formed in the charged particle generating electrode. A first electric field, in which the charged particle generating electrode is positive and the charged particle extract electrode is negative, is generated to emit ions from the raw material at the charged particle generating electrode. In the electron generation mode, supplying the raw material from the raw-material supply section is stopped. A second electric field, in which the charged particle generating electrode is negative and the charged particle extract electrode is positive, is generated to emit electrons from the raw material at the charged particle generating electrode.

    Abstract: The MoSi2 heating element has not been so resistant under the low-temperature heating, because the low-temperature oxidation, which is attributable to the grain boundary oxidation, occurred. In the present invention, long life under the low-temperature heating is attained by the following two structures. (1) The MoSi2 grains have a network structure and are linked three dimensionally. (2) The secondary, silica-bearing oxide or glass phase forms a net-like structure around the MoSi2 grains.

    Abstract: An image forming apparatus which forms a halftone image on a print medium by using a multipass process to scan a printhead N (N is an integer of 2 or more) times in a single area on the print medium and form dots by each scan operation includes a pass division unit which sets the print density of a scan operation in the first pass so as to prevent dots from overlapping with each other on the print medium, and sets the print densities of scan operations in the second to Nth passes, a tone reduction unit which generates print data of the respective scan operations in accordance with the print densities set by the pass division unit, and a printhead which prints a halftone image on a print medium on the basis of the print data generated by the tone reduction unit.
