Abstract
An image forming device includes an image forming unit and a thermal fixing unit. The image forming unit uses a plurality of different color developing agents to form a color image on a recording medium. The plurality of different color developing agents are configured from binding resins with the same thermal properties. The plurality of different color developing agents include at least a high-resistance developing agent and a low-resistance developing agent. The high-resistance developing agent has a higher electrical resistance than the low-resistance developing agent and a lower charge-to-mass ratio than the low-resistance developing agent. The thermal fixing unit thermally fixes the color image onto the recording medium.
Claims15
An image forming device comprising:
- an image forming unit that uses a plurality of different color developing agents to form a color image on a recording medium, each of the plurality of different color developing agents having a different electrical resistance and a volume resistance;
- and
- a thermal fixing unit including a heating member and a pressing member, the heating member contacting a surface of the recording medium formed with the color image, the pressing member pressing the heating member through pressing contact with an opposite surface of the recording medium, the heating member and the pressing member having surface resistances different from each other.
