Filed: 2007-10-15
Abstract: <P>PROBLEM TO BE SOLVED: To prevent the deterioration of image quality in the region where a toner layer of higher optical absorbance is formed in fixing a toner image formed using toners of two colors or more by radiating flash light to it without expanding the device size or complicating the configuration.  <P>SOLUTION: A toner of Y color is adhered on the surface of a K toner layer which is continuous by a predetermined length or more in the x-direction and the y-direction and of which K density is greater than a predetermined value with a film Y density depending on the K density (refer to (C)). The flash light radiated to the sites coated with the toner of Y color when the flash light is radiated, is attenuated by a part of it being absorbed by the toner of Y color while transmitting through the Y toner layer, reaches the K toner layer, and is absorbed on the surface of the K toner layer (refer to (D)). Thus, increase in the surface temperature of the K toner layer is suppressed, and differences in temperature between the upper layer side and the lower layer side in the K toner layer immediately after the radiation of the flash light become small. Thereby, the occurrences of sublimation or smoke emission of a toner, voids, etc. can be reduced.  <P>COPYRIGHT: (C)2009,JPO&INPIT
