Apparatus for control of flow of toning to reveal a latent image on a film eletrostatica eletrofotografico and to reveal a latent image on a portion eletrostatica partial preGiven a film eletrofotografico

摘要

A toner flow control system for liquid toner within camera/processor apparatus includes the disposition of a development electrode portion (30) and the electrophotographic film (14) within planes inclined with respect to a horizontal plane at an angle of between 30 and 60. degree.. The film (14) and electrode (30) define a toner flow channel (32) therebetween which is also therefore inclined with respect to the horizontal plane at the same angle, whereby the flow of the liquid toner (36) through the channel (32) is able to be controlled and uniformly distributed over the electrode (30) and film (14). In addition, gravity discharge (46) of the toner (36) from the channel (32) is able to be accomplished without the need for special sealing devices to confine the toner within the toner cell. The controlled flow of the toner within the channel (32) eliminates the need for substantial negative pressure or vacuum suction systems normally employed in conjunction with vertically oriented toner channels.
