In this paper, a magnetic field analysis of a bonded magnet roller for laser printer is presented. The magnetization direction of bonded magnet is decided by the flux distribution of injection mold during the manufacturing process. The injection mold is designed and analysed to fit design specification. The experiment shows that the flux distributions of magnet roller agree with the given specifications.
