Imaging apparatus and process with intermediate transfer element |
(57) Disclosed is an imaging apparatus which comprises an imaging member, a means for
generating an electrostatic latent image on the imaging member, a means for developing
the latent image, an intermediate transfer element having a charge relaxation time
of no more than about 2 × 10² seconds to which the developed image can be transferred
from the imaging member, and a means for transferring the developed image from the
intermediate transfer element to a substrate. Also disclosed is an imaging process
which comprises generating an electrostatic latent image on an imaging member, developing
the latent image, transferring the developed image to an intermediate transfer element
having a charge relaxation time of no more than about 2 × 10² seconds, which enables
the transfer with very high transfer efficiency of the developed image from the intermediate
transfer element to a substrate.
