A magnetic toner and a method of developing using same are described. The toner comprises a magnetic material and a resin comprising a polymeric esterification product of a dicarboxylic acid and a diol comprising a diphenol. This toner is particularly useful in flash fusing systems. The diphenol reactant has the following structure <CHEM> wherein R represents a substituted or unsubstituted alkylene radical having from 2 to 12 carbon atoms, an alkylidene radical having from 1 to 12 carbon atoms or a cycloalkylidene radical having from 3 to 12 carbon atoms; R min and R sec each represent a substituted or unsubstituted alkylene radical having from 2 to 12 carbon atoms, an alkylene arylene radical having from 8 to 12 carbon atoms or an arylene radical; X and X min represent hydrogen or an alkylradical having from 1 to 4 carbon atoms; and n1 and n2 are each at least 1 and the average sum of n1 and n2 is less than 21. |
