WAXY ORGANOPOLYSILOXANE AND TONER COMPOSITION CONTAINING THE SAME

摘要

A waxy organopolysiloxane having a long chain alkyl group or a heteroatom-containing long chain organic group, wherein in a heat absorption curve obtained by the measurement of heat absorption characteristics by means of a differential scanning calorimeter, the area of a heat absorption peak for a fraction melting at a temperature range of 50 DEG C or less accounts for 50 % or less of the total peak area. Incorporation of the waxy organopolysiloxane into a toner for developing an image of electrostatic charge can provide a toner which is free from the occurrence of an offsetting phenomenon or a sheet wrapping phenomenon even when an image is fixed by the heating roller fixing method at a high speed.
