PROBLEM TO BE SOLVED: To provide an image forming device, image forming method, and process cartridge which prevent jitter caused by vibration, etc., of a photoreceptor drum and image forming device and also prevent variations in ruled line width and density even in electrophotographic image formation in which small, uniform particle-diameter toner is used, exposure is carried out with a laser beam exposure system, and satisfactory dot reproducibility is assured. SOLUTION: A mass adding body is disposed in the electrophotographic photoreceptor having a photoconductive layer on a cylindrical conductive support. Additionally, toner in which the variation coefficient of the shape factor is 16% or less and the number variation coefficient of the number particle size distribution is 27% or less is used. |
