Toner for Developing Electrostatic Latent Image

2 A toner for developing electrostatic latent images comprising a colored resin particle containing a binder resin, a colorant and a parting agent, and an external additive, wherein a volume average particle diameter (Dv) is 4 to 10 μm and an average circularity is in the range of 0.93 to 0.995; an arithmetic average roughness Ra of a surface of the toner is in the range of 0.05 to 0.3 μm; a 10-point average roughness of the surface of the toner is in the range of 0.5 to 2.5 μm; an angle of repose is in the range of 10 to 35°; and a transformation ratio of the toner applied with a pressure of 1 mN/mmfor 5 seconds by means of a microcompression tester is 20% or less. The toner has an excellent balance between offset and low-temperature fixing performance and an excellent shelf stability when used in a high-printing speed printer. And, by using the toner, an image can be formed without deteriorating image quality by environmental change, and excellent cleaning ability can be provided.
