  • Color-blind melt flow index properties for toners
    Patent number: 6406822
    Abstract: At least three differently colored toners, designed for use together in forming a color image in an image developing device, have substantially the same melt flow index value. By substantially matching the melt flow index values of at least three toners of a set of toners, it has been found that the resultant color image has an overall excellent image quality, i.e., an excellent overall gloss level without any gloss banding.
