EXTERNAL ADDITIVE FOR TONER AND TONER

An external additive for toner comprising a particle of a silicon polymer having a siloxane bond and a Si-O-C bond, wherein in an FT-IR spectrum of the external additive obtained by an ATR method, a maximum peak is present in a range of from 1030 cm−1 to 1070 cm−1, where an average intensity in a ra...
