| Electrostatic imaging
occurs when a light source or other means is used to create a pattern
of static electric charges on an imaging surface. In many machine
designs, the image is made visible using a "developer",
a mixture of colored toner particles and magnetic "carrier"
beads. The carrier beads have surface properties that impart either
a positive or negative triboelectric charge to the toner. A system
of magnets and rollers is used to move the developer powder to deposit
its toner on the latent image.
Since 1986, VERTEX
IMAGE PRODUCTS, INC. has supplied commercial and custom
carrier powders used in copiers and printers in the reprographics
industry. Our expertise allows us to impart and control both positive
and negative charge polarities to a wide range of toner types. Our
carriers have found use in electrophotographic systems including
copiers, printers, microfilm systems, "blueprint" duplicators,
and MICR (Magnetic Image Character Recognition) conversion systems.
Successful carriers have been produced using core materials that
are metals and metal oxides, sponge or solid, spheres or flakes,
conductive or resistive, coarse or fine. Our family of possible
coating materials includes oxide layers, styrene/acrylics, vinyls,
silicones, and fluoropolymers.
Vertex is now located
in a growing facility in western Pennsylvania. We work with toner
producers and others to design a compatible carrier for specific
needs. We welcome anyone who has developer problems to allow us
to help find a technical solution.
