Electrophotography and Development Physics (eBook, PDF)

• Format: PDF

Produktbeschreibung

Electrophotography and Development Physics focuses on the complicated and increasingly important technology found in photocopiers and laser printers. An introduction chapter acquaints the reader with the technical history of electrophotography, its current and projected markets, and also alternative related copying and printing technologies. A concise descriptionof the physics of the complete electrophotgraphic process is followed by an in-depth treatment of static electricity. The three types of developmentsystems (two component, monocomponent, and liquid), and their associated charging mechanisms. In this second edition, a discussion of the new color copiers and a chapter updating the original material have been added. On mastering this material, which is presented in a manner suitable for both the newcomer and the established expert, the reader will have a workingknowledge of the electrophotographic process and a detailed knowledge of its important subsystem, development.
