PURPOSE: To provide an electrophotographic process and an electrophotographic device capable of suppressing the abraded amount of a photoreceptor by the durability, capable of suppressing the increase of remaining potential, excellent in durability and stability, and capable of obtaining a good image. CONSTITUTION: In this electrophotographic process, a primary electrifier means and a transferring and electrifying means are arranged in contact with each other, and the electrophotographic device is electrified by impressing only a direct voltage to the photoreceptor from an electrifier member at both time of primary electrification and transferring electrification. The relation among a current value Z(μA) per 10cm of a transfer electrifier, a process speed (x)(mm/ sec) and the peripheral length (y)(mm) of the photoreceptor satisfies expressions (1) Z<=7.28×10<-4>×x×y-0.687 and (2) Z>=1.46×10<-4>×x×y--0.137.
