Abstract
Piezoelectric properties of materials, such as, polyvinylidene fluoride (PVDF) are used to generate surface potentials that are adequate for the xerographic transfer function. A web of PVDF is used to form a transfer intermediate belt. The magnitude and direction of fields generated around the belt can be controlled by judicious location of field neutralizing devices and the direction, location and magnitude of the belt strain. Toner images are first transferred onto the belt and then transferred from the belt onto copy sheets without the need for high voltage power supplies.
Claims15
Apparatus for forming toner images on an image receiving member and transferring the toner images from the image receiving member to copy sheets, comprising:
- at least one image forming device including an image receiving member;
- and
- a transfer apparatus including a transfer intermediate member having piezoelectric properties for transferring the images from said image receiving member to said transfer intermediate member and subsequently transferring the images from said transfer intermediate member to copy sheets.
A method for forming toner images on an image receiving member and transferring the toner images from the image receiving member to copy sheets, comprising:
- forming images with at least one image forming device;
- placing the images with said image forming device onto an image receiving member;
- positioning a transfer apparatus adjacent the image receiving member with said transfer apparatus including a transfer intermediate member having piezoelectric properties for transferring the images from said image receiving member to said transfer intermediate member;
- and
- transferring the images from said intermediate member to copy sheets.
A device for transferring images from an imaged source to a copy sheet, comprising:
- a transfer intermediate member, and wherein said transfer intermediate member includes piezoelectric properties for transferring the images from the imaged source to said intermediate member and subsequently transferring the images from said intermediate member to copy sheets.
