IMAGE FORMING METHOD, IMAGE FORMING APPARATUS, AND DEVELOPER

摘要

An image forming method of forming an image by transferring a toner image, which is formed on an image bearing member by toner particles, to a transfer medium is provided. The toner particles include a coloring agent and a resin. When an average electrostatic adhesive force Fe of the toner particles to the image bearing member is expressed by the following expression, a/r satisfies 0.2<=a/r<=0.7: $F_e=\frac{{\varepsilon }^{\text{'}}-1}{{\varepsilon }^{\text{'}}+1}.\frac{q^2r^2}{4{{\mathrm{pi\varepsilon }}_0\left(r^2-a^2\right)}^2}$ where epsilon' is a specific dielectric constant of the image bearing member, q is an electrification quantity per one toner particle, and r is a volume average radius of the toner particles.
