摘要： Disclosed are a toner for electrostatic image development which is able to realize enough charge stability over a long period of time as deterioration of a toner due to mechanical stress is prevented in a developing unit, and to prevent generation of filming, and an image forming method using the same.The toner for electrostatic image development contains toner particles and an external additive. The external additive includes silica fine particles whose surface is covered with a number of projections, and a number average particle diameter of the silica fine particles is 80 to 200 nm. The external additive may include small-diameter fine particles for external additive having a number average particle diameter of 5 to 45 nm.
