徴とする請求項１記載の現像システム。[Claims for Utility Model Registration] (1) A photoreceptor drum on which a visible image is formed by a developer from a latent image formed on its surface, and a photoreceptor drum in which the developer is attached to the photoreceptor drum by a developing roller. In a developing system that includes a developing device that performs development and a biasing device that biases the developing device toward the photosensitive drum, the photosensitive drum is sandwiched between the developing point and the developing roller, and At least one pair of rollers arranged so as to abut on a first positioning means having a constant positional relationship with the drum and a second positioning means having a constant positional relationship with the developing roller, and an interval between the rollers. A developing system comprising: a regulating means for finely adjusting regulation. (2) The developing system according to claim 1, wherein the first positioning means is a drum guide for the photosensitive drum, and the second positioning means is a bearing for the shaft of the developing roller.
