More Information
Summary:The utility model relates to a conductive structure of a charging roller, which comprises a charging roller arranged close to a waste powder bin, a conductive sheet arranged on the end wall of the waste powder bin, a conductive bracket and an elastic piece, the support is sleeved outside the charging roller, and the elastic piece is arranged between the conducting strip and the support in an elastic deformation mode. According to the conductive structure of the charging roller, indirect electric connection between the conductive sheet and the charging roller is achieved through the elastic piece and the support, the reliability and stability of electric connection can be guaranteed through the elastic effect of the elastic piece, the situation that discontinuous electrification occurs due to poor contact between the conductive sheet and the charging roller is improved, and the image quality stability is effectively improved. The utility model further relates to an imaging device which comprises a waste powder
