    摘要： An image is generated by exposing the surface to a scanning laser beam in accordance with an image forming process. The intermediate image transfer member receives the image from the image carrying member and transfers it onto a recording sheet. The memory stores a plurality of values of process line speeds A for defining a speed of an image forming process in a sub-scanning direction, and a plurality of values of process line speeds B for defining a speed of the image transfer process. The controller makes a plurality of combinations of the process line speeds A and B by arbitrarily selecting one of the plurality of values of selectable process line speeds. According to another aspect, a voltage sensor detects a voltage of the photoconductor, a toner deposition sensor detects an amount of toner deposition on the photoconductor member, a charging member provides a charge onto the photoconductor, a grid adjusting member controls a grid voltage of the charging member, a laser exposure unit exposes the photoconductor to a laser beam, an exposure adjusting member adjusts an amount of a laser beam exposure, and a development gamma detect member detects a development gamma line by performing a sequential operation. A reference table includes information to determine appropriate voltage values of the photoconductor, a development bias and an after-exposure voltage of the photoconductor in accordance with the development gamma line obtained with the development gamma detect member. A controller detects the voltage of the photoconductor rotating in each of the process line speeds and determines optimum values of the grid voltage of the charging member and the amount of laser beam exposure from the laser exposure unit to obtain the respective required voltage level used by the grid adjusting member, and the after-exposure voltage used by the exposure adjusting member, on the basis of the detected voltage and with reference to the information included in the reference table.

    摘要： A color registration-pattern formed between continuous printing pages with different magnifications is read so as to correct color misalignment by converting the magnification into the reference magnification so as to calculate the present color misalignment correction. Thereby, a plurality of the color registration-patterns with different magnifications, which are formed between continuous printing pages with differentiated magnifications by the speed change of a polygon-mirror motor can be read so as to correct the color misalignment.
