Abstract: When conducting a color-shift-correcting mode using a registration mark formed by the image forming section on an image carrier, the image detecting section outputs the image detection signal representing the line width of the registration mark and the control section calculates the line width of the registration mark from the image detection signal. The control section compares a line width of the registration mark with a predetermined reference value of the line width to discriminate between abnormality and normality. If normality, the control section continues the color-shift-correcting mode and if abnormality the control section conducts the image forming system restoration mode after stopping the execution of the color-shift-correcting mode. Therefore, even in the case where a white spot is generated for some reasons on the registration mark, the color-shift-correcting mode can be conducted on the normal registration mark with the help of the image forming system restoration mode.
