Abstract

An imaging member comprises a softenable layer in contact with a conductive substrate, the softenabie layer containing a layer of photosensitive particles. The member is used to accomplish migration imaging. The layer of photosensitive particles is normally at or near one side of the softenable layer. An electrostatic latent image is established in the photosensitive particles by uniformly charging one surface of the softenable layer and exposing the photosensitive particles in the layer to imagewise actinic radiation. Upon softening of the layer the photosensitive particles migrate toward the conductive substrate. The non-light-struck photosensitive particles remain in place in the softened layer and a visible image is formed,

An imaging member comprises a softenable layer in contact with
a conductive substrate, the softenabie layer containing a
layer of photosensitive particles. The member is used to
accomplish migration imaging. The layer of photosensitive
particles is normally at or near one side of the softenable
layer. An electrostatic latent image is established in the
photosensitive particles by uniformly charging one surface of
the softenable layer and exposing the photosensitive particles
in the layer to imagewise actinic radiation. Upon softening
of the layer the photosensitive particles migrate toward the
conductive substrate. The non-light-struck photosensitive
particles remain in place in the softened layer and a visible
image is formed,

It is sometimes necessary and desirable to change an electro-
static latent image which has been formed in such a softenabie
layer prior to development. A method for erasing a first
electrostatic latent image prior to forming a subsequent such
image comprises electrically charging the imaging member to a
polarity opposite the polarity of the first electrostatic
latent image to bring the member in the imaging area portions
to at least about 0 potential.

The imaging member can then be re-imaged with a subsequent
image and developed by softening the softenable layer as
described above.
