PROBLEM TO BE SOLVED: To provide a protective layer forming device that protects a photoconductor even when the linear speed of the photoconductor is high, and forms high-quality image that does not have a black stripe due to an increase in resistance of a charging roller, and also to provide an image forming apparatus and process cartridge using the protective layer forming device. SOLUTION: This protective layer forming device has; a protective agent block containing a metal soap; a pressing unit for pressing a protective agent supplying means against the protective agent block; and a protective agent supplying means for supplying a protective agent onto a photoconductor. The protective agent supplying means is rotated while being pressed against the protective agent block by the protective agent supplying means, and the protective agent block is micronized to make the protective agent in the form of fine powder, and the protective agent in the form of fine powder is supplied onto the photoconductor, thereby forming a protective layer. The protective agent in the form of fine powder has a particle diameter of 200μm or smaller and contains protective agent particles of 20 to 200μm in an amount of 1% by mass to 70% by mass.
