Abstract
Dry toner particles comprising an amorphous complex macromolecular compound that contains in its macromolecular structure, (i) a polyester backbone (A) having a Tg of at least 45.degree. C. and (ii) at least one polymer chain (B) being attached to the backbone, either terminally and/or in a side-chain, the polymer chain (B) being derived from a polymer selected from the group consisting of polyolefines and polyolefines containing alkoxy groups which on itself has an average molecular weight by number (M.sub.avg) so that 1900.ltoreq.M.sub.avg <4000, a melting point between 50.degree. C. and 150.degree. C. and a melting range of at most 15.degree. C.
