LONG CHAIN ALKYL MODIFIED POLYORGANOSILOXANE AND TONER COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a toner never causing offset phenomenon or adhering to roller phenomenon of sheet even at high speed on fixing by the heat roller fixing method. SOLUTION: The toner comprises as an inner releasing agent a long chain alkyl modified organopolysiloxane having at least one long chain alkyl group of 18 to 200 carbons, and containing 50% or less area of endothermic peak of a fraction melting at 50 deg.C or lower to the total area of all peaks on the measurement of endothermic characteristic by the differential scanning calorimeter.
