To provide a toner which ensures uniform dispersion of a wax present in the toner and is excellent in printed image properties and electrostatic charge properties by controlling the dispersion diameter of the wax.

Toner particles containing at least one toner resin and at least one wax, are provided. The wax present in the toner particles has an average domain size of about 1 micron or less. Developer systems, two component, and monocomponent, are further provided as well development systems and methods for developing an electrostatic image.
