2,540 dpi Full Color Image Creation with a Liquid Electrophotography System

Extremely high-resolution images have been obtained by an electrophotographic imaging system using liquid toner. This system includes a high-resolution Laser Scanning Unit (LSU) with a 2,540 dpi resolution, and an image transfer system that does not use electrical energy. We examined the characteristics of high-resolution image creation, in particular the relationship with laser beam focusing and laser power to obtain the optimized parameter value of the LSU. The image pattern from this system was confirmed to be accurate according to the resolution. Furthermore, an examination of the noiseless transferability of “shearing transfer” showed the accuracy of the created image was due not only to the development process, but also to the transfer process. We attempted to print a full-color image with this system, and obtained a real 2,540 dpi color image, which is equal in quality to that produced by offset printing.
