Abstract:
1. An image forming apparatus comprising: at least one image bearing member; at least one charging device configured to charge a surface of the at least one image bearing member; at least one developing device configured to develop an electrostatic latent image on the surface of the at least one image bearing member with a developer including a toner to form a toner image thereon; and a toner image transporter configured to receive the toner image from the at least one image bearing member to transport the toner image; wherein a surface of the toner image transporter has a coefficient of static friction that is greater than or equal to the coefficient of static friction of the surface of the at least one image bearing member, wherein the toner has a volume average particle diameter (Dv) of from 3 to 7 μm, a ratio (Dv/Dn) of the volume average particle diameter (Dv) to a number average particle diameter (Dn) of from 1.00 to 1.40, a form factor SF- wherein the toner includes a lubricant having a particle diameter of from 0.5 to 5 μm.
