TONER FOR MAGNETIC INK CHARACTER RECOGNITION PRINTING

摘要

PURPOSE:To obtain a toner excellent in preservability and forming a clear toner image by fixation by blending a toner for magnetic ink character recognition printing contg. polystyrene resin or polyester resin as the principal component of a binder with Fischer-Tropsch wax having a specified mol.wt. and specified thermal characteristics. CONSTITUTION:This toner contains polystyrene resin or polyester resin as the principal component of a binder, particles of a magnetic material and Fischer-Tropsch wax having a wt. average mol.wt. of >=1,000 and endothermic bottom peak values measured by DSC in the range of 100-120 deg.C.
