摘要： An electrophotographic image forming method includes a charging step, an exposure step, a developing step and a transfer step in the rotation of an electrostatic latent image bearing member, in which a process speed of the electrostatic latent image bearing member is 200 to 500 mm/sec, an outer diameter of the electrostatic latent image bearing member is 15 to 35 mm, an outer diameter of a developer bearing member is 10 to 25 mm, and a magnetic single component developer of which the residual magnetization in a measured magnetic field of 796 kA/m is 0.5 to 5.0 Am2/kg is used as the developer. The electrophotographic image forming method can provide a good image quality without causing scattering of toner in downsizing, weight reduction of an electrophotographic apparatus and speed-up of an electrophotographic process.
