  DOI :  10.2352/ISSN.2169-4451.1998.14.1.art00015_2  Published OnlineJanuary 1998

This present research relates to a toner comprised the new polyester resin for electrophotography which is used in copiers, printers, fax machines or multifunction devices utilizing heat-roll fixing.This polyester resin was prepared by synthesizing a linear polyester resin having low molecular weight peak top in a range of 1×103 to 1×104, and then cross-linking with dicarboxylic acid component having long chain structure and polyol component having four hydroxyl groups.This resin has a low molecular weight peak top and widened molecular weight distribution. The toner comprised this resin showed excellent fixing properties at low temperature without losing anti-offset up to 220°C. Then, it was concluded that the polyester resin is an useful toner binder for the contact heated fixing process.
