Abstract
Provided is a developing toner for electrostatic latent images capable of coping with the size reduction of an image forming apparatus and decrease of the consumption amount, not shortening the working life of a photoreceptor, less causing paper jam, background fogging, etc., excellent in various characteristics required for the toner, and capable of forming images of good picture quality. The developing toner being used when images are formed to a recording material in an image forming apparatus comprising an image forming station, a recording material feeding station, an image fixing station and a controlling station, the developing toner for electrostatic latent images containing hydrophobic fluidizing particles deposited to the surface of coloring resin particles comprising a binder resin containing a polyester resin, a polyalkylene, a polyolefin dispersant and a non-oxidized polyethylene resin, and an inorganic pigment, and having time constant τ of from 100 to 350 msec.
