Abstract (en)
A flowable, dry powder of particles of a developing composition are provided. The compositions may be either heat or pressure-fixable and utilize from about 0.4 to 3 parts by weight of fluorinated carbon per 100 parts by weight of a thermoplastic binder and a magnetically responsive material. The fluorinated carbon has a degree of fluorination in the range of 10% to 63% and an average diameter below about 2 microns. The developing powder compositions possess improved flow humidity resistance and provide dramatically improved copy quality.
