电摄影是本世纪五十年代才发展起来的一门崭新的摄影技术,具有普通银盐感光材料所无法比拟的许多优点,引起了世界各国的广泛重视,发展十分迅速,已成为现代摄影中一个重要的新分支。涂有树脂膜的玻璃珠、塑料珠、金属珠(直径0.2-0.8毫米)或细铁粉(140-300目)。近来,人们又研制出了许多新颖的静电摄影材料。二、成象过程电摄影是利用光导体材料在曝光前后电阻率迅速变化所产生的静电潜象,吸附带异性电荷的树脂微粒而成象的原理进行录象的,如图1所示。璐咚州一、电摄影材料光导体是电摄影的关键材料,它起感光
Electrophotography is a brand new photographic technique developed in the 1950s. It has many advantages unmatched by common silver salt photosensitive materials, has attracted the attention of all countries in the world and has developed rapidly. It has become a modern photography Important new branch. Resin film-coated glass beads, plastic beads, metal beads (0.2-0.8 mm in diameter) or fine iron powder (140-300 mesh). Recently, people have also developed many novel electrophotographic materials. Second, the imaging process Electrophotography is the use of photoconductor material before and after exposure to rapid changes in the resistivity of the electrostatic latent image, the adsorption of heterophile charged resin particles imaging principle, as shown in Figure 1. Timbuktu First, photographic materials Photoconductor is the key material for electrophotography, it plays a sensible
