发明名称 Method and means for hydraulic meniscus toning of ferro electric materials
摘要 To predispose toner particles to develop latent images in the form of polarized domains on a ferro-electric recording layer (12), for immediate transfer to a substrate (S), a donor roller (1) is rotated in a bath of liquid dispersed toner particles (4), which are charged; the thickness of the liquid dispersion, and hence of the quantity of donor particles, is controlled by limiting the amount of dispersant liquid toner particle deposit by rotating a limiting roller (9) positioned spaced apart with respect to said donor roller by a tiny gap; sequential rotation of the donor roller past a nkp (14) with the ferro-electric surface layer (12) forms a meniscu between the toner dispersion and, where the polarization of domains of the ferro-electric recording member (12) is opposite the charge polarization of the toner particles, the toner particles will adhere to the ferro-electric recording surface (12) for subsequent transfer to the recording substrate (S).
