ABSTRACT:
In electrostatic recording apparatus recording head such as an optical fiber tube (OFT) is closely spaced from the image forming member, such as a drum covered with a photosensitive substance. The electrostatic latent image is generally formed with the use of a toner applied to the drum. Despite the use of various cleaning devices, toner particles are carried by the drum into the narrow gap between the OFT and the drum and adhere to the scanning face of the OFT, interfering with the projected image. The present invention provides a manual or automatic cleaning device positioned in the narrow gap for removing adherent toner or other interfering material from the scanning face of the OFT.
