摘要:
An image forming apparatus, including: an electrostatic latent image bearing member; an electrostatic latent image forming unit configured to form an electrostatic latent image on the electrostatic latent image bearing member; and a developing unit containing a toner and configured to develop the electrostatic latent image with the toner to thereby form a visible image, wherein the developing unit is a contact type one-component developing unit which includes a toner bearing member being in contact with the electrostatic latent image bearing member, wherein a contact pressure between the electrostatic latent image bearing member and the toner bearing member is 2.0×104 N/m2 to 7.5×104 N/m2, wherein the toner contains a binder resin and a releasing agent, and wherein an extracted amount of the releasing agent extracted with hexane from the toner is 10 mg/g to 25 mg/g.
