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 × 10 4 N/m 2 to 7.5 × 10 4 N/m 2 ,
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. |
