Patent ID: 7056635

Claim:
A toner comprising: a thermoplastic resin; a colorant; a wax; and a crystalline polymer, wherein at least one of the following formulas (I) or (II) is satisfied: Tg ( W T )< Tg ( W W )−2° C. (I) Tg ( CP T )< Tg ( CP CP )−2° C. (II), wherein Tg(W T ) and Tg(W W ) are the DSC endothermic peak temperatures in ° C. of the wax measured in the toner and the wax measured alone, respectively and Tg(CP T ) and Tg(CP CP ) are the DSC endothermic peak temperatures in ° C. of the crystalline polymer measured in the toner and the crystalline polymer measured alone, respectively, wherein a heating rate of the DSC measurement is 10° C./min; wherein a CuK α X-ray diffraction spectrum of the crystalline polymer comprises a plurality of diffraction peaks, and wherein the diffraction peaks are observed at Bragg (2θ) angles of at least 19 to 20°, 21 to 22°, 23 to 25° and 29 to 31° wherein said angles may vary by ±0.2°.
