Estimating the term…
A developing apparatus for image forming equipment capable of insuring images with high resolution while preserving tonality. A developing sleeve is provided with conductive portions and insulative portions on its surface by knurling. A magnetic roller is accommodated in the sleeve to constitute a developing roller. A toner supply roller is held in contact with the developing sleeve. A doctor blade is disposed above and spaced apart by a predetermined distance from the developing sleeve and made of a magnetic material. Bias applying means applies an alternating voltage to the sleeve to effect reversal development.
A developing apparatus facing an image carrier, the image carrier carrying an electrostatic latent image, and having a developer carrier facing said image carrier, the developer carrier carrying a magnetic developer and generating numerous microfields on a surface thereof, and voltage applying means for applying an alternating electric field to a developing position to apply a bias for development, said apparatus comprising:
