Abstract

PURPOSE:To precisely form an image on a specified position by detecting the position of a register mark in the midst of forming the image and correcting the position of the image on an image carrier in the midst of forming the image based on the detection signal. CONSTITUTION:The image 33 is formed on a belt 8 and the crossed register marks 16 and 17 are continuously formed out of an image area (on both sides of the image 33) in a moving direction of the belt (simultaneously with the image) in an electrophotography method, then the belt 8 proceeds in a direction shown with an arrow 11. Pickup elements 14 and 15 pick up the marks 16 and 17 in a timing when the register marks 16 and 17 primarily pass pickup points 14a and 15a (fixed) based on the sequence signal from a sequence controller. When the arrival of the marks 16 and 17 at the pickup points is later than an ideal timing, the quantity of delay is detected from a mark pickup signal in the timing when the marks primarily pass. Based on the quantity of the delay, the phase of a DELAY(CV) signal is made to proceed and the timing of a vertical synchronizing signal is advanced by reducing the value of the margin register. The slurring of color can be corrected.
