た請求項１記載の構造。[Claims for Utility Model Registration] 1. A fixing roller gear coaxially fixed to one end of the fixing roller, an idle gear removably meshing with the fixing roller gear, a power transmission gear meshing with the idle gear, and a spring It consists of a pivoting lever that is elastically biased and pivoted at the middle, one end of which is engaged with the support shaft of the idle gear, and the other end of the pivoting lever is pressed in conjunction with the opening and closing of the machine cover. The structure of the fuser drive unit allows pressure to be applied and released. 2 When a pressing force that resists the elasticity of the spring is applied to the other end of the pivot lever, the idle gear meshes with the fixing roller gear, and when the pressing force is released, the restoring elasticity of the spring engages the idle gear. 2. The structure according to claim 1, wherein the fixing roller gear is separated from the fixing roller gear.
