ELECTROSTATIC IMAGE DEVELOPING TONER

摘要

Provided is an electrostatic image developing toner having toner mother particles containing a binder resin and a releasing agent, wherein the binder resin contains an amorphous vinyl resin and a crystalline polyester resin; the releasing agent contains a first releasing agent component containing an ester wax and a second releasing agent component containing a microcrystalline wax; a content of the first releasing agent component in the releasing agent is in the range of 40 to 98 mass %; a content of the second releasing agent component in the releasing agent is in the range of 2 to 60 mass %; and a content of the crystalline polyester resin in the binder resin is in the range of 5 to 20 mass %.
