摘要： A single-component developing method with the steps of forming a uniform developer layer and developing an electrostatic latent image. The uniform developer layer is formed by abutting a layer regulating member made of a plate of soft, elastic material against a developer carrier and by regulating the developer layer by urging at least one end edge on a portion of the layer regulating member against the devloper carrier. The electrostatic latent image is formed on a photosensitive material and is developed by moving a portion of the developer carrier with the uniform developer layer formed thereon opposite the photosensitive material.
