Abstract
An image-forming device such as a full color printer is provided which is designed to correct the speed of a conveyer belt on which print sheets are transported or intervals between image-transferring units for compensating for a shift between colors. The image-forming device has a timer which measures an elapsed time from turning on of the device or release of a sleep mode, a print-off time and a print time and determines a correction value as a function of the times measured by the timer by look-up using a table.
