ABSTRACT:
A developing and fusing apparatus for applying a single component magnetically responsive dry particulate toner powder to a latent electrostatic image on electrostatic copy paper and fusing the thusly applied toner powder onto the surface of the copy paper with the developing section of the apparatus having a permanent magnet applicator roll assembly which moves the toner powder about the periphery thereof into the vicinity of the copy paper to transfer the toner powder onto the copy paper with the amount of toner powder passing around the applicator roll assembly being controlled by doctor blades, and a cartridge which dispenses the toner powder onto the applicator roll assembly for passage around the applicator roll assembly. The fusing section of the apparatus includes a pair of fusing rolls which are urged toward each other with sufficient force to pressure fuse the toner powder onto the surface of the copy paper along with means for limiting the movement of the fuser rolls toward each other to prevent the fusing roll surfaces from actually contacing each other.
