摘要： An electrophotographic image forming method including a toner image transfer step and eliminating an independent step for cleaning transfer residual toner is operated without causing ghost images and with good gradation and dot reproducibilities. In the method, the photosensitive member is exposed at an exposure intensity which is at least a minimum exposure intensity and below a maximum exposure intensity. The minimum exposure intensity is determined on a surface potential-exposure intensity characteristic curve of the photosensitive member by determining a first slope S1 of a straight line connecting a point giving a dark part potential Vd and a point giving a value of (Vd+ a residual potential Vr)/2, determining a contact point between a tangent line having a slope of S1/20 and the surface potential-exposure intensity characteristic curve and determining the minimum exposure intensity as an exposure intensity at the contact point. The maximum exposure intensity is determined as 5 times a half-attenuation exposure intensity.

The toner carrying member has a base whose surface has an average surface roughness (Ra) of 1.0 to 3.0 .mu.m. A resin coating containing electrically conductive fine particles is formed on the base surface at a density of 4 to 12 g per 1 m.sup.2. The outer layer of the coating has an Ra from 0.8 to 3.0 .mu.m. The toner carrying member carries an electrically insulating magnetic toner containing at least a binder resin and a magnetic component, and satisfying the conditions of a volumetric average particle size of 4.5 to 8 .mu.m, a BET specific surface area of 1.8 to 3.5 m.sup.2 /g, a charge amount of -20 to -35 .mu.c/g, a loose-state apparent density of 0.40 to 0.52 g/cm.sup.3, and a true specific gravity of 1.45 to 1.8. The magnetic toner is formed into a layer having a thickness smaller than the dimension of the gap by a member for regulating the thickness by pressing the toner against the toner carrying member. The magnetic toner is then conveyed to the development section, in which the toner develops the electrostatic image while an AC electric field is applied.
