ABSTRACT:
A method for the generation of a brush of developer powder at a magnet cylinder of a developing apparatus in a copying machine, for the development of a latent image, generated particularly electrostatically wherein developer powder is being thrown at least partly directly at the magnet cylinder in distribution over the length of this magnet cylinder and optionally passing this brush through a narrow gap. In the developing apparatus at least one scoop wheel or one or several pairs of scoop wheels rotating in an inclined plane and being partly immersed in a supply of developer powder serve to throw developer powder at the magnet cylinder for the generation of the brush of developer powder thereon. With the scoop wheel may be associated a worm conveyor and baffles.
