ABSTRACT:
An image forming method, including charging a photoreceptor with a charger contacting thereto; irradiating the photoreceptor to form an electrostatic latent image thereon; developing the electrostatic latent image with a toner to form a toner image on the photoreceptor; transferring the toner image onto a recording material directly or through an intermediate transferer; and fixing the toner image on the recording material, wherein the toner includes a binder resin; a colorant; a composition having a low softening point; and an external additive, and wherein a surface resistivity Rse [Ω] of the charger and a volume resistivity Rsw [Ω·cm] of the composition having a low softening point satisfy the following relationship:in-line-formulae description="In-line Formulae" end="lead"?0.8×10−1Rse<Rvw<1.5×10Rse.in-line-formulae description="In-line Formulae" end="tail"?
