A toner for electrostatic image development, containing a resin binder and a wax, wherein the resin binder contains an amorphous polyester obtained by polycondensing a carboxylic acid component containing fumaric acid in an amount of from 55 to 100% by mole, with an alcohol component, wherein the wax contains an ester of pentaerythritol and a fatty acid having 15 to 25 carbon atoms, and a method of forming fixed images, including the step of applying the toner for electrostatic image development to a non-contact fixing type image-forming apparatus. The toner for electrostatic image development of the present invention is suitably used for, for example, developing a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
