摘要： In the image forming apparatus, a color shift correction execution check unit detects positions of density correction patches of respective colors according to binary signals of density detection outputs by a density sensor on the density correction patches. When distances corresponding to intervals of time from starts of image drawing of the density correction patches of the respective colors to the detection of the positions of the density correction patches of the respective colors and distances between the density correction patches of the respective colors are shifted from a value, the color shift correction execution check unit determines color shift correction processing is required to be executed, and it gives an instruction to a color shift correction control unit to execute the color shift correction processing. And the color shift correction control unit forms a color shift correction patch to execute the color shift correction processing.

摘要： A prediction table is stored in an NVM and an in-apparatus temperature is measured by a temperature sensor, a registration control adjustment based on the prediction table is carried out if an absolute value of a variation in the in-apparatus temperature is smaller than a threshold, and a registration adjusting patch is formed to actually measure a positional shift amount if the absolute value of the variation in the in-apparatus temperature is equal to or greater than the threshold. When the positional shift amount measured actually is greatly different from a value of the prediction table, the value of the prediction table is modified into the actually measured value.
