Abstract

Inventia se refera la un dispozitiv de developare cu perii magnetice pentru developarea imaginilor electrostatice, utilizate în electrofotografie, xerografie sau scris cu laser. Dispozitivul de developare, conform inventiei, este prevazut cu un foto-tambur si cu mai multi cilindri din material nemagnetic pentru transportul materialului de developare, în fiecare cilindru de transport fiind fixat cîte un dispozitiv magnetic care, sunt magnetizate diferitm o cada ce contine materialul de developare în care se cufundî primul cilindru de transport dispozitivele magnetice fiind magnetizate diferit pe partea opusa fototamburului în directia de transport dispozitivele magnetice fiind magnetizate diferit pe partea opusa fototamburului în directia de transport a developatorului fiind magnetizater în lungul a trei linii polare decalate cu 120 degree în sensul circumferintei acestora si anume în lungul primei linii polare în sens contrar magnetizîrii la celelalte doua linii polarem pe ultimul cilindru de transport în sensul de transport al developatorului, fiind dispus un cutit de curatire în asa fel încît materialul de developare aflat pe suprafata cilindrului, este distribuit cu o grosime uniforma.The invention relates to a magnetic brush development device for the development of electrostatic images, used in electrophotography, xerography or laser writing. According to the invention, the inventive device is provided with a photo drum and multiple cylinders of non-magnetic material for transporting the developing material, in which each transporting cylinder is fixed to a magnetic device which is magnetized differently by a tub containing the material of development in which the first transport roller is immersed, the magnetic devices being magnetized differently on the opposite side of the phototrader in the transport direction, the magnetic devices being magnetized differently on the opposite side of the phototube in the transport direction of the developer being a magnetiser along three polar lines deformed by 120 degrees in the direction of their circumference, namely along the first polar line in opposite direction to the magnetization on the other two polair lines on the last transporting cylinder in the transporting direction of the developer, there being arranged a cleaning knife in such a way that the developmental material on the surface of the cylinder is distributed in a uniform thickness.
