EMULSION, TONER FOR ELECTROPHOTOGRAPHY, DEVELOPER, AND METHOD FOR IMAGE FORMATION

摘要

PROBLEM TO BE SOLVED: To provide a toner which is used for developing an electrostatic charged image, can make a low temperature fixing and has a strong document offset-proof property. SOLUTION: The emulsion contains as a main component a crystalline resin whose melt viscosity (at melting point + 20°C) is not less than 10 Pa s and not more than 10,000 Pa s and is obtainable by polymerizing an emulsion which can be obtained by dispersing in an aqueous medium a mixture of the crystalline resin and a radically polymerizable monomer which forms an amorphous polymer. The toner, the electrostatic charged image developer and the method for image formation are all using the emulsion. COPYRIGHT: (C)2005,JPO&NCIPI
