    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.
