Abstract
The invention provides a toner for electrostatic image development having at least a binder resin and a colorant and having an existence ratio of an IA Group element, from which hydrogen is excluded, measured by XPS (X-ray Photoelectron Spectroscopy) in a range of about 0.03 to 1.0 atom % and a total of existence ratios of an IIA Group element, an IIIB Group element and an IVB Group element, from which carbon is excluded, measured by XPS in a range of about 0.05 to 2.0 atom %. The invention further provides an electrostatic image developer having at least a carrier and the toner, and an image forming method including at least developing an electrostatic latent image with a developer containing at least the toner to form a toner image.
