Abstract
Disclosed is an oil-less toner composition exhibiting good low temperature release and stripping in fixing, enhanced surface gloss of fixed image, and/or OHP transparency. By controlling one or more properties, such as the relative thermal energy input during the EA aggregation/coalescence process, using a wax having a certain dispersion size (D50), molecular weight and/or melting temperature, the toner particle produced thereby can achieve optimal surface wax protrusion with a surface wax content of about 12 to about 25 weight percent. This is based on the total amount of wax in the toner, as determined by x-ray photoelectron spectroscopy (XPS). The contamination of wax on developing rolls, photoreceptor and carriers, which lowers the reliability of the developer, is suppressed with the present exemplary embodiment.
