20130004204 | COLOR IMAGE FORMING APPARATUS - An image forming apparatus includes a process unit arranged in the vicinity of the circumference of each photosensitive member and the process unit is configured to act on the photosensitive member in forming a toner image thereon. The image forming apparatus detects a time period since a laser beam emission unit emits a laser beam to the photosensitive member to form an electrostatic latent image for detection until the formed electrostatic latent image for detection or a toner image based on the electrostatic latent image for detection reaches the process unit, and performs color misregistration correction control based on the result of detection. In this case, a control unit at least decreases the light amount of a pre-exposure LED when the electrostatic latent image for detection passes through a position facing the pre-exposure LED. | 2013-01-03 |
20130004205 | SURFACE COATINGS FOR THE BIAS CHARGING ROLLER - Various embodiments provide materials and methods for bias charging members including an outer surface coating overlaying an outer base layer, wherein the outer surface coating can include conductive fillers combined with one or more polymers to provide desirable surface, electrical, and/or mechanical properties. | 2013-01-03 |
