DEFINITION

Classification: 399/130

IMAGE FORMATION:

(under the class definition) Subject matter wherein a copy is produced by making a latent image visible with toner or marking particles.

(1) Note. This subject matter also includes a second or subsequent exposure or development of the same image to enhance the reproduction.
