Patent ID: 8722303

Claim:
An image forming method comprising: a step of forming an electrostatic latent image on a surface of an electrostatic latent image bearing member, and a step of developing the electrostatic latent image by using a two component developer carried on a developer carrying member to form a toner image, wherein, in the development, a surface circumferential speed of the electrostatic latent image bearing member is not less than 300 mm/s, a developing bias, in which an alternating electric field is superimposed on a DC electric field, is applied to the developer carrying member, and the peak-to-peak voltage of an AC component in the developing bias is not more than 1.3 kV, the two component developer comprises a toner and a magnetic carrier, the magnetic carrier comprises a magnetic core and a resin, and the magnetic core is a ferrite containing Sr and Ca, and in a backscattered electron image of a cross section of the magnetic carrier captured by a scanning electron microscope, i) an area ratio of a ferrite portion is not less than 0.70 and not more than 0.90, and ii) a number average area of a ferrite crystal is not less than 2.0 μm 2 and not more than 7.0 μm 2 .
