摘要:
A magnetic developing process for use in electrophotographic or electrostatic recording techniques employs a magnetic brush formed by a developer which comprises a powder mixture of a low resistance toner and a high resistance toner, at least one of which comprises a magnetic toner. Both toners are triboelectrically charged, and the magnetic toner serves as a carrier, so that both toners are attracted to an electrostatic image to provide a developing thereof.

摘要:
A developing apparatus in a transfer-type electrophotographic system having a photosensitive body, wherein the developing apparatus includes a developing roller spaced a small distance from the photosensitive body for supplying a developing solution to the photosensitive body to develop a latent image thereon and to induce a potential on the developing roller through the developing solution from the photosensitive body. A cleaning member is held against the developing roller. In one embodiment, the potential of the developing roller is limited to a level intermediate between predetermined upper and lower limits, an a developing roller is switched into an electrically floating condition except during development of an image. In another embodiment, a developing bias potential is produced responsive to the potential of the developing roller. The bias potential is then applied to the developing roller which is used as a developing electrode.
