<p>PROBLEM TO BE SOLVED: To widen the range of a fixation temperature range, in which an offsetting phenomenon and a sheet winding phenomenon do not occur, to a lower temperature side, to improve fixability and to enhance blocking resistance and flowability by incorporating specified polysiloxane. SOLUTION: This toner contains modified polysiloxane having repeating units (a) and (b) represented by formulae, in which R<1> is 1-6C straight chain or branched chain alkyl or 6-12C aryl, preferably 1-6C alkyl, phenyl or naphthyl, more preferably 1-4C alkyl or phenyl, particularly preferably methyl, R<2> is a straight chain or branched chain hydrocarbon having an average carbon number of 6-200, preferably straight chain or branched chain saturated hydrocarbon preferably having an average carbon number of 12-100, in particular 16-80 and provided that, the number of carbon in R<2> is limited to one having larger number of carbon than R<1> .</p> |
