Abstract
An image-forming process for forming a full-color image including: forming a full-color toner image by supplying at least a cyan toner, a magenta toner, and a yellow toner onto a recording medium; and fixing the toner image on the recording medium by flash fusing, wherein each of the cyan toner, the magenta toner and the yellow toner contains an infrared absorbent, the cyan toner is supplied so that out of the cyan toner, the magenta toner and the yellow toner, the cyan toner is positioned in the uppermost layer in areas of the toner image where cyan toner is present, and the flash fusing is performed by a delayed light emission process wherein a plurality of flash lamps emit lights at a time interval.
Claims22
An image-forming process for forming a full-color image comprising:
- forming a full-color toner image by supplying at least a cyan toner, a magenta toner and a yellow toner onto a recording medium;
- and
- fixing the toner image on the recording medium by flash fusing, wherein:
- each of the cyan toner, the magenta toner and the yellow toner contains an infrared absorbent;
- the cyan toner is supplied so that out of the cyan toner, the magenta toner and the yellow toner, the cyan toner is positioned in an uppermost layer in areas of the toner image where the cyan toner is present;
- and
- the flash fusing is performed by a delayed light emission process wherein a plurality of flash lamps emit lights at a time interval, wherein the content amount of the infrared absorbent in the cyan toner is smaller than the respective content amounts of the infrared absorbent in the magenta toner and the yellow toner.
An image-forming process for forming a full-color image comprising:
- forming a full-color toner image by supplying at least a cyan toner, a magenta toner and a yellow toner onto a recording medium;
- and
- fixing the toner image on the recording medium by flash fusing, wherein:
- each of the cyan toner, the magenta toner and the yellow toner contains an infrared absorbent;
- the yellow toner is supplied so that out of the cyan toner, the magenta toner and the yellow toner, the yellow toner is positioned in a lowermost layer in areas of the toner image where the yellow toner is present;
- and
- the flash fusing is performed by a delayed light emission process wherein a plurality of flash lamps emit lights at a time interval, wherein the content amount of the infrared absorbent in the cyan toner is smaller than the respective content amounts of the infrared absorbent in the magenta toner and the yellow toner.
An image-forming apparatus for forming a full-color toner image, comprising:
- a toner image-forming device for forming a full-color toner image by supplying at least a cyan toner, a magenta toner and a yellow toner onto a recording medium;
- and
- an image fixing device for fixing the toner image on the recording medium by flash fusing, wherein:
- each of the cyan toner, the magenta toner and the yellow toner contains an infrared absorbent;
