Patent ID: 8139984

Claim:
An image forming apparatus, comprising: a photoreceptor; a charger having a surface resistivity, configured to charge the photoreceptor with a charger contacting thereto; an irradiator configured to irradiate the photoreceptor to form an electrostatic latent image thereon; an image developer containing a toner, which is configured to develop the electrostatic latent image with the toner to form a toner image on the photoreceptor; a transferer configured to transfer the toner image onto a recording material directly or through an intermediate transferer; and a fixer configured to fix the toner image on the recording material, wherein the toner of the image developer comprises: a binder resin; a colorant; a composition having a low softening point; and an external additive, and wherein the 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: 0.8×10 −1 Rse<Rvw< 1.5×10 Rse.
