Abstract In order to prevent toner leaks from both sides of a developing roller disposed within a case accommodating polymerized toner, side seals each having a TEFLON(R) (polytetrafluoroethylene) felt member on its surface are provided to make sliding contact with a surface of the developing roller. In addition, 'Hanarl FL-Z75' manufactured by Kanto Kasei Ltd., is used as a lubricating agent for the TEFLON(R) felt members to make them more lubricative. Accordingly, noise generated by the side seals sliding contact with the developing roller can be reduced. To prevent toner leaks from the sides of the developing roller, a film or resin stopper is disposed at a lower-end front edge of the case to stop the toner.
