IMAGE FORMING METHOD, TONER, DEVELOPER, PRINTED PRODUCT, TONER STORAGE UNIT, AND IMAGE FORMING APPARATUS

WIPO Patent Application WO/2022/172630

A1

An image forming method includes forming an electrostatic latent image on an electrostatic latent image bearer, developing the electrostatic image with a toner to form a visible image, transferring the visible image onto a recording medium, and fixing the transferred visible image on the recording medium. The toner includes toner base particles each including a binder resin, a release agent, and particles of an inorganic antibacterial antiviral agent, and satisfies conditions (1) to (3) below. The image forming method satisfies a relationship of 2.0X (micrometers)≦Z≦2.5X (micrometers). Conditions (1) the number average particle diameter X of the particles of the inorganic antibacterial antiviral agent is 1.5 (micrometers)≦X≦2.5 (micrometers), (2) 3X (micrometers)≦Y≦4X (micrometers), and (3) an amount of the inorganic antibacterial antiviral agent in the toner is 2.8% by mass or greater, but 5.0% by mass or less.
