NONMAGNETIC UNICOMPONENT DEVELOPING TONER

摘要

PROBLEM TO BE SOLVED: To provide a nonmagnetic unicomponent developing toner superior in fixability and offset resistance and stably chargeable even in the case of successive printing and capable of obtaining good images and superior in durability. SOLUTION: This nonmagnetic unicomponent developing toner is characterized by containing a polyester resin obtained by polymerizing (A) a monoepoxy compound and a polyepoxy compound having >=5 epoxy groups, (B) a 2-4-valent polyol, and (C) at least one kind of saturated polybasic acid compound selected from groups comprising a 2-4-valent saturated polybasic acid and its anhydride and one or more kinds of polybasic saturated acid compounds obtained from these lower alkyl esters.
