摘要： An image forming apparatus includes an electrostatic latent image bearer, an electrostatic latent image former, a developing device, a transfer device, and a fixing device. The electrostatic latent image former forms an electrostatic latent image on the electrostatic latent image bearer. The developing device develops the electrostatic latent image with a developer to form a toner image. The transfer device transfers the toner image on a recording medium. The fixing device fixes the toner image on the recording medium. The developer contains an adhesive medium and foamable particles.

摘要： 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.
