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.

摘要： A toner is provided. The toner includes a crosslinked polyester resin, and a block copolymer. The crosslinked polyester resin includes a diol component, which includes an aliphatic diol component having 3 to 10 carbon atoms in an amount of 50% by mole, and a crosslinked component, which is at least one of a crosslinked component of an aliphatic alcohol having three or more valences and a crosslinked component of an aliphatic acid having three or more valences, and the block copolymer includes a crystalline segment (a) and a non-crystalline segment (b). The toner has a first glass transition temperature (Tg1st) of from 20° C. to 50° C., which is determined by subjecting the toner to differential scanning calorimetry (DSC) and measuring a glass transition temperature in a first temperature rising process in the differential scanning calorimetry (DSC).

摘要： A developing device including a developer bearing member containing a magnetic field generator having multiple magnetic poles and a developer containing chamber is provided. The developer containing chamber contains a two-component developer comprising magnetic carrier particles having a saturated magnetization of 58 to 70 emu/g in a magnetic field of 1KOe and toner particles, and has a divider to define an upper supply chamber and a lower collection chamber. The supply chamber includes a supply conveyer to supply the two-component developer to the developer bearing member at an upstream side from the developing area. The collection chamber includes a collection conveyer to collect the two-component developer from the developer bearing member at a downstream side from the developing area. The multiple magnetic poles includes three developer bearing poles capable of bearing the developer on its surface.
