Abstract
A process and apparatus for developing an electrostatic latent image on a surface of a strip-type photoconductor. A working supply of developer material, held readily available for application to the photoconductor, is carried from a holding device to the photoconductor by means of a rotatable applicator. A magnet, magnetically coupled to the applicator, brings the developer material on the applicator into sufficient contact with the photoconductor to cause the developer material to brush the image bearing surface of the photoconductor, thereby developing the latent image on the same. The developer material is collected before being returned to the working supply, and fed to the middle of the working supply to facilitate mixture and blending therewith. In an electrostatic copier, including a replenishing supply of developer material, the above apparatus has provision for mixing replenishing developer material with the developer material collected from the applicator, before feeding the resulting mixture to the working supply.
