Abstract
PURPOSE:To widen the permissible width of the spacing between a nonmagnetic ear height regulating member and a developing sleeve provided with a developing magnet and prevent developing trouble, by providing a ferromagnetic member to part of said regulating member. CONSTITUTION:An ear height regulating member 10 regulating the ear height of a magnetic brush 9 is provided in opposition to a developing sleeve 7 provided with a developing magnet 8. This member 10 is formed of a nonmagnetic member 10a and a knifelike ferromagnetic member 10b. The member 10b is fixed to the side face on the front side of the member 10a in the moving direction of the brush 9 and is so fixed that the knifelike leading end thereof has a spacing larger than the spacing of the member 10a with respect to the circumferential surface of the sleeve 7. In this way, the clogging of the cohered toner or the like in the spacing between the circumferential surface of the sleeve 7 and the ear height regulating member is made difficult, the permissible width of said spacing is made wider and developing trouble is prevented.
