<p>PROBLEM TO BE SOLVED: To provide a device for image formation and a toner such that splashing or trailing after fixing is prevented, melt sticking of the toner on a latent image carrying body in a low humidity environment is prevented and images of high quality can be formed. SOLUTION: In the device for image formation to heat and fix a developed image on a recording material through a heat-resistant fixing thin film, the toner used is prepared by externally adding at least inorganic fine particles 1 consisting of at least one kind selected from oxides of titanium, aluminum, zinc and zirconium having 80 to 800 nm average primary particle size, inorganic fine particles 2 except for silica and having <80 nm average primary particle size, and silica fine particles having <30 nm average primary particle size. The developed image with the toner is fixed by heating.</p> |
