Developing apparatus.

摘要

Disclosed is a developing apparatus for developing an electrostatic latent image on a latent image carrier by supplying the latent image carrier with a developer. This developing apparatus includes a toner accommodating chamber for accommodating magnetic toners. The apparatus also includes a developing roller 24, having a plurality of fixed magnetic pole members 240 and sleeves 241 provided along peripheries of the fixed magnetic pole members 240 and rotating thereabouts, for feeding the developer composed of magnetic carrier and magnetic toner to the latent image carrier. The apparatus further includes a developing chamber 230 having a partition wall 230-4 formed along the developing roller 24 and assuming a configuration adapted to a shape of the developer roller 24, and a toner supply port 235 for supplying the magnetic toner to the developing chamber 230 from the toner accommodating chamber. <IMAGE>
