DEFINITION

Classification: 399/252

Dry development:

(under subclass 222) Subject matter wherein a dry developer material is applied to render the latent image visible.

(1) Note. Dry developer material may be toner particles (magnetic or nonmagnetic) mixed with magnetic particles that act as carriers under the influence of a magnetic field.

(2) Note. For example, this subject matter may include immersion of the latent image in dry toner. For immersion with liquid toner, see SEARCH THIS CLASS, SUBCLASS in this subclass.
