Patent ID: 7267920

Claim:
A toner for developing an electrostatic latent image comprising of toner particles comprising a binder resin, a colorant and a releasing agent, wherein: a volume-average particle diameter of the toner particles is in a range of about 5 μm to 8 μm and an average of shape factor SF1 thereof is in a range of about 125 to 140; and an arithmetical mean undulation height of the surface of the toner particles at the 90% point on the cumulative distribution curve is in a range of about 0.15 μm to 0.25 μm, wherein a ratio of a number-average grain size distribution index GSDp of the toner particles to a volume average grain size distribution index GSDv of the toner particles (GSDp/GSDv) is about 0.95 or more.
