Patent ID: 8623581

Claim:
An electrostatic image developing toner comprising: toner particles each comprising a binder resin and a colorant; and an external additive carried on the toner particles, wherein the toner particles each have protrusions on a surface thereof, wherein an average of lengths of long sides of the protrusions is 0.10 μm or more but less than 0.50 μm, a standard deviation of the lengths of the long sides of the protrusions is 0.20 or less, and a coverage rate of the protrusions on the surface of each toner particle is 30% to 90%, wherein the external additive comprises at least two different fine particles comprising external additive (A) and one or more external additives (B), and wherein the external additive (A) has a longest average primary particle diameter among the external additives and is charged to have the opposite polarity to that of the toner particles, and at least one of the one or more external additives (B) is charged to have the same polarity as that of the toner particles.
