摘要： A method and apparatus for forming an image reduce the processing load on a video controller. A CPU causes a counter to start counting the optical beam detection signals of a photodiode in accordance with a signal which indicates the leading edge of a sheet of recording paper received from a TOP sensor. Comparators compare the count value issued from the counter with the values set by the CPU at registers. Based on the comparison result, an F/F sets Q output. Thus, a BD signal is issued through a gate during a period specified by the values set at the registers. The use of the BD signal reduces the processing load on the video controller which generates and transfers an image signal.

摘要： In an image printing operation, advance sheet feeding is performed if the size of a recording medium is known upon feeding at least one sheet of the recording medium. To the contrary, advance sheet feeding is not performed if the size of a recording medium is not known, for example, immediately after a power supply has been turned on or after a new supply of recording medium has been placed in a sheet feeding unit.

摘要： A color image formation system in which transfer means for sequentially receiving plural color images is idled if raster image data for a color has not yet been converted from a page description language into the raster image. A page description language or other code data for a first color is converted into a raster image of the first color and an electrophotographic process is commenced whereby a laser beam is modulated in accordance with the raster image of the first color and the image formed by the modulated laser beam is transferred to rotatable transfer means. After image formation in the first color is complete, code data for the second color is converted into raster image data. If conversion of the second color is not yet complete but the transfer means has rotated to a position where it is ready to receive the second color, the transfer means is idled by continued rotation thereof and forcibly restricting laser beam illumination whereby the transfer means is fed blank to a predetermined position. The transfer means is idled until the conversion of second color is complete, whereafter the laser beam is modulated in accordance with the raster image of the second color to form the second color on the transfer means. Processing for third and subsequent colors is continued as above until a full color image has been formed on the transfer means.

摘要： The present invention has an object to provide an image forming apparatus and method which enables an operator to easily adjust to the desired printing density. A paper feeding roller is driven in timing along with a registration roller. The irradiation of a modulated laser beam is started, a developing high-voltage is changed from "0" V to a predetermined voltage V1, and the voltage is changed to V2 at other timings. By sequentially changing the voltage in this manner, the printing densities from laser modulating data d1 to d10 are adjusted and printing in different densities can be performed.

摘要： A beam recorder comprises a beam generator, a deflector for deflecting the beam to scan the beam, and a light intensity control unit for controlling a light intensity of the beam. The deflection has a plurality of deflection planes to which the beam is directed, and at least one of the deflection planes in a non-scan plane. The light intensity control is effected by utilizing a period in which the beam is directed to the non-scan plane.

摘要： To solve a problem of an increase of kinds of toner patches required for an adjustment accompanying an increase of kinds of half tones to be coped with that results from an intention of acquiring more stable image by forming the toner patches between paper sheets. It becomes possible to form more toner patches and therefore to deal with an increase of kinds of toner patches by correcting a density in a space of a line count obtained by summing up a line count corresponding to a space between paper sheets during a continuous printing operation, a rear-end blank line count of the n-th page, and a leading-end blank line count of the (n+1)th page that is enabled by comparing the size of a recording material and the size of pixel data and thereby by identifying a blank portion of the recording material.
