Abstract
The present invention provides a toner for developing an electrostatic latent image comprising of: toner particles containing at least 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 to 8 μm; an average of shape factor SF1 of the toner particles 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 to 0.25 μm. Further, the present invention provides an electrostatic latent image developer containing the toner. The invention also provides a method for producing the toner.
