(57) [Summary] [Problem] Heat resistance, durability, storage stability, and fluidity are good, and it is difficult to reduce the life of a developer due to carrier spent by toner and the life of a photoconductor due to filming of a photoconductor by toner. Provided is a toner for developing an electrostatic image. A weight average molecular weight (Mw) exceeding 1.5 / A wax having a number average molecular weight (Mn), a melt viscosity at 140 ° C. of less than 10 mPa · s and a crystallinity of more than 75% to 85% or less, and a weight average molecular weight (Mw) of 1.5 or less / Number average molecular weight (Mn), 140 A toner for developing an electrostatic image containing a wax having a melt viscosity at 10 ° C. of less than 10 mPa · s and a crystallinity of more than 85% and 95% or less. |
