Title: Color image forming apparatus
Inventor: MIYAZAKI RIE
IPC: G03G15/01
Filed: 2002-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a high temperature offset of toner in color image formation obtained by superposing and thermally fixing the toner having a plurality of colors.  <P>SOLUTION: In heat fixing, the toner having three colors of yellow, magenta and cyan is superposed and transferred sequentially on a transfer material 6, and the yellow (Y) toner 13Y is toner facing the fixing surface of a heating roller 8a. Then, the external additive isolation rate of the yellow toner 13Y being the toner facing the fixing surface is larger than the external additive isolation rates of the toner 13M and 13C of other colors, and is set to the maximum. Thereby, many isolated external additives of the toner 13Y are present between the toner 13Y and the fixing surface, which improves release properties of toner and prevents the high temperature offset of toner.  <P>COPYRIGHT: (C)2004,JPO

A duct whirling and collecting mechanism is provided on the downstream side of the heat exchanger on the discharge side of the blower, and the medium gas blown out from the blower is supplied to the discharge section through the dust whirling and collecting mechanism. The medium gas containing the particle-like foreign matters such as dust which is introduced through a medium gas entrance line 11 moves from up to down, while whirling, in a whirling section line 12. At that time, foreign matters which have a specific gravity larger than that of the medium gas are centrifugal separated, to fall down through a slit 15 into a dust collecting section 17 and accumulate there. A shaft for whirling the gas might be set up in a horizontal direction. The foreign matters could be separated, with the gas pressure varied according to a diameter of the foreign matters.  <P>COPYRIGHT: (C)2004,JPO
