Abstract
A toner flow control system for liquid toner within camera/processor apparatus includes the disposition of a development electrode portion (30, 130, 230) and the electrophotographic film element (14, 114, 214) within planes inclined with respect to a horizontal plane at an angle of between 30.degree. and 60.degree.. A toner flow channel (32, 132, 232) is defined between the development electrode and the film element wherein, as a result of the inclination of the channel, the flow of the liquid toner (36, 136, 236) is able to be controlled and uniformly distributed over the electrode and film element under the influence of gravity. In addition, gravity discharge of the toner is able to be accomplished without any auxiliary devices from the lower free edge portion (46) of the film element (14) when the film element is a roll cassette, while when the film element is an aperture card (114) or a microfiche (214), discharge of the toner from within the vicinity of the lower edge portions (149, 249) of such film element image frames (114, 214) is able to be achieved by means of a passive plate (145, 245) disposed in a non-contact mode with respect to the lower edge portions of the film image frames as a result of surface tension forces developed and defined between the passive plate and the liquid toner.
