Title: Electrophotographic apparatus
Inventor: TAKAGI ATSUSHI
IPC: G03G15/043
Filed: 1981-12-15
Abstract: PURPOSE:To prevent attachment of toner to nonimage areas and occurrence of blank memory, by separately adjusting luminance of each of plural light sources composing light sources for blanly exposing a photoreceptor after forming a latent image in order to uniformly expose it. CONSTITUTION:A rotating cylindrical photoreceptor is exposed to an optical original image, and then, at the time of reversing an illumination system, blank exposure is executed with a plurality of light source lamps 21-2n arranged in the longitudinal direction of the photoreceptor. Each lamp 2i is connected with variable resistors 121-12n in series and each resistance is controlled to prevent uneven illumination due to unevenness of the lamps 2i and error of the installation positions, thus permitting excess of toner to be removed from nonimage areas, and a blanc memory to be prevented in the next copy, and a sharp copy to be made. A similar effect can be obtained by providing a slit unillustrated before each lamp 2i and controlling its aperture to eliminate illumination unevenness.

Next, a determination is made as to whether the boiler is an in-furnace denitration boiler or a multi-fuel burning boiler, and if it is an in-furnace denitration boiler, the air/fuel ratio for respective boiler stages is adjusted by corrective the NOX master signal. If it is a multi-fuel burning boiler, the W/B air quantity for respective boiler stages is adjusted. In this manner, the opening of the W/B inlet damper is adjusted and corrected to provide the optimum air/fuel ratio for a low NOX operation.
