Patent ID: 8206879

Claim:
An image forming method comprising: charging surfaces of latent electrostatic image bearing members; exposing the charged surfaces of the latent electrostatic image bearing members so as to form latent electrostatic images corresponding to each color; developing the latent electrostatic images using developers of four colors so as to form each color toner image; and transferring each toner image from the latent electrostatic image bearing members to an intermediate transfer belt applying a pressure so as to form a color image, wherein during said developing, a toner is used that has an interparticle adhesion force of 500 nN to 1,200 nN when pressed at 500 nN and a volume average particle diameter of 4 μm to 8 μm, and during said transferring, an applied pressure is 20 N/m to 60 N/m, and wherein a tandem image forming apparatus is used in the image forming method.
