PURPOSE:To prevent adverse influence by a magnetic carrier and to perform development to high density by scattering a developer by a magnetic member on the outside circumference of a non-magnetic sleeve and generating powder smoke by the toner separated from the carrier of the two-component type developer. CONSTITUTION:The magnetic brush of a two-component type developer 9 formed to a non-magnetic sleeve 10a by a magnet roll 10 is forced to scatter from one end to the other end of a magnetic member 15 provided to the sleeve 10a. The chain bond of the magnetic carriers 9a of the developer 9 is released by such scattering by which the powder smoke consisting of the toner 9b alone is generated and the latent image on a recording drum is developed. The adverse influence by the magnetic carrier is prevented and the high-density development is executed by such constitution. |
