Abstract
To prevent irregular print density resulting from an uneven toner layer, a developer remover which may be a plurality of cylindrical members formed like rollers, a net-like member, roller member and/or a contact member, are arranged in a manner to contact a sponge roller When residual toner on the surface of a developing roller is scraped off by the sponge roller the developer remover pushes the toner away without allowing the toner to clot inside the sponge roller Consequently, the sponge roller's performance to remove toner from itself to the developing roller can be preserved for a long time.
