MONOCOMPONENT DEVELOPING TONER FOR OILLESS FIXING, IMAGE FORMING METHOD USING IT, IMAGE FORMING DEVICE, AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a monocomponent developing toner for oilless fixing that can efficiently and evenly perform feeding of a toner between a feed roller and a developing roller in a developing apparatus of an image forming means using oilless fixing, thereby suppressing image density unevenness and achieving superior image stability without causing faulty charging.

SOLUTION: The monocomponent developing toner for oilless fixing includes at least a wax-containing resin, a coloring material and an external additive agent. The total energy calculated from a torque generated when a screw blade is made to rotatably enter a toner powder layer and move in the toner powder layer is 450-530 mJ at the blade rotation speed of 100 mm/s, and the rate of the total energy at the blade rotation speed of 10 mm/s to the total energy at the blade rotation speed of 100 mm/s is 2.0-3.0.
