    摘要： A process for preparing a toner includes forming an emulsion with a buffer solution and an amorphous biodegradable polyester resin represented by Formula (1): wherein each n independently represents an integer of 1 to about 20 and x and y represent respective ratios of respective monomeric units and x ranges from about 0 to about 1000 and y ranges from about 0 to about 300; adding a colorant, a coagulant, and optionally a wax to the emulsion to form a mixture; heating the mixture, permitting aggregation and coalescence of the mixture to form toner particles; and recovering the toner particles.

    摘要： A toner composition is provided which contains a polyester resin with hydrophilic groups and hydrophobic end groups and a colorant, wherein said polyester resin is of the formula: wherein R is an alkylene group; X is an aromatic hydrocarbon; Y is selected from the group consisting of an alkali and an alkaline earth metal salt of an arylenesulfonate or an alkylenesulfonate; R′ is a hydrophobic group, and m and n represent the number of random segments of from about 50 to about 300 for n, and from about 20 to about 2,000 for m, and m is less than 20 times n.
