Abstract
A toner for developing an electrostatic image, a developer for developing an electrostatic image, a process for producing them, and a process for forming an image that provide excellent developing and transferring performance and also provide excellent performance stability, as well as high image quality and reliability are provided. The problem can be solved by a toner for developing an electrostatic image having a particle size distribution index on a small particle side GSDpS in number distribution of a particle diameter of about 1.27 or less, GSDpS is D50p/D16p, D50p represents a particle diameter providing, a particle diameter accumulation in number distribution of 50%, and D16p represents a particle diameter providing a particle diameter accumulation in number distribution of 16% from a small diameter side.
