Toner for electrostatic image development and image forming method employing the same

摘要

The present invention provides a toner for electrostatic image development which reconciles anti-offset properties and fixation properties and is superior in resistance to abrasion and peel of the fixed image in uses where the development and fixation are conducted at a wide range of a fixing speed, particularly high speed which exceeds 20 or 30 m/min. The toner comprises a polyester resin, a colorant, and a releasing agent, wherein the flow beginning temperature Tfb of the toner as measured by a constant load extrusion type capillary rheometer is within a range of 70-105 DEG C and the flow ending temperature Tend is within a range of 120-144 DEG C.
