Abstract: A particle feed arrangement for applying solid particles contained in a picle storage tank to an image carrier of a non-impact printer. The arrangement includes a conveying member in the form of an endless screw conveyor 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 peripheral extremities of the endless screw to cause the particles to be collected in the trough.
