<p>An apparatus for producing an electrographic print on a photosensitive receptor (3) placed on a holder (1) so as to produce an electrostatic latent image on the receptor by projecting light thereon, the apparatus comprising a developing unit (7) located below the receptor holder, the developing unit including a developing section (7c), the developing unit or the receptor holder being movable in relation to the other, the developing section supplying a developer (27) to the sensitive receptor so as to make the electrostatic latent image visible; and means (8, 11, 12, 14) for collecting the used developer from the sensitive receptor, the collecting means including a pneumatic knife (8) for blowing the used developer on the sensitive receptor to a place of collection, and means (11, 18) for receiving the used developer (19) brought by the pneumatic knife, the receiving means being provided on that surface of the receptor holder which is outside the sensitive receptor, the receiving means being provided in a direction perpendicularly to the direction (D) in which the receptor holder or the developing unit is moved.</p> |
