Abstract
A particle feed arrangement for applying solid particles contained in a particle storage tank to an image carrier of a non-impact printer. The arrangement includes a conveying member disposed to pass within a particle supply source to feed the particles to the vicinity of a surface of the carrier. A deflector is interposed between the carrier and the conveying member to collect the particles conveyed by the member. The deflector has one of its edges arranged in the immediate vicinity of the said carrier to form, in conjunction with the carrier, a trough of generally prismatic shape in which the particles so collected accumulate. The other edge of the deflector, which is formed by a rectangular plate, is virtually in contact with the surface of a particle conveying member to cause the particles to be collected in the trough. The carrier is movable in a direction in which it carries the particles towards the edge of the said prism which is spaced from the surface of the carrier to allow the particles which are carried past this edge to remain applied only to the sensitized zones of the said image carrier and excess unapplied particles to be returned to the supply source.
