Document Type and Number:
Japanese Patent JP2944203
Kind Code:
B2
Abstract:
Scavenging apparatus for removing substantially all unwanted particles from the image and non-image areas of an electrostatographic imaging member without appreciable adverse effects on the desired image remaining thereon, includes an alternating pole magnetic roller for rotatably creating a fast changing magnetic field, a stationary ac biased shell for enclosing the magnetic roller and for creating a low, but fast changing electrostatic field, and a low vacuum system. This apparatus combines the effects of such magnetic and electrostatic fields with those of the low vacuum system to gently loosen and effectively remove unwanted particles from the imaging member, without resort to relatively strong electrostatic field and vacuum values that are likely to adversely affect the desired loose toner image still on the imaging member.
