摘要： An image forming apparatus performs electrophotographic image forming using a toner and includes an image bearing member configured to bear an electrostatic latent image on a surface thereof, a developing mechanism configured to develop the electrostatic latent image in to a toner image by using a toner, a transfer mechanism configured to transfer the toner image from the image bearing member to an image receiver, a cleaning mechanism including a cleaning blade and configured to remove a residual toner on the image bearing member after toner image is transferred to the image receiver. The toner includes a binder resin and a colorant, forms a toner powder layer, and satisfies an inequality Y≧−0.05X+0.029, in which “X” expresses a porosity of the toner powder layer after uniformly compressed at a constant force and “Y” expresses a torque value obtained by rotatably sticking a conical rotor into the toner powder layer.

摘要： An image forming apparatus includes a contact charging member which contacts a surface of an image carrier member in order to charge the surface of the image carrier member, and a cleaning member which contacts and slides on a surface of the contact charging member in order to clean the surface of the contact charging member. The image forming apparatus performs a function in such a way that after an electrostatic latent image is produced on the image carrier member which is in a charged state, toner powder is supplied to the image carrier member by a developing device in order to make the electrostatic latent image visible and then a visualized image is transferred to a transfer member. In the image forming apparatus, a maximum height of concavities and convexities formed on the surface of the contact charging member is equal to or less than an average particle diameter of the toner powder supplied by the developing device.
