Claims

[Claim for Utility Model Registration] A developing roller is disposed at a position corresponding to the photoreceptor drum, a stirring roller is disposed close to the developing roller, and the stirring roller agitates the developer in the housing. In an apparatus using a two-component developer configured to frictionally charge a carrier and a carrier so that the developer adheres around a developing roller, Consisting of at least four groove-shaped bucket members arranged at equal angles and fixed at both ends, and a paddle supported by the bucket members, the paddles are connected to bucket members facing each other across the axis of the stirring roller. 1. A stirring roller device for a developing device, characterized in that both ends of the member are fixedly held, and adjacent paddles are held alternately by a combination of different bucket members.
