An image forming apparatus includes: an image forming unit; a communication unit configured to receive image data and an instruction; a nonvolatile memory configured to store color correction data; a color correction data generating unit configured to generate a new color correction data and update the color correction data stored in the nonvolatile memory with the new color correction data; and a control unit. When the instruction contains a first instruction which instructs performing the printing operation without updating the color correction data, the control unit corrects a gradation of an image contained in the image data using existing color correction data stored in the nonvolatile memory. When the instruction does not contain the first instruction and also when a given condition is satisfied, the control unit causes the color correction data generating unit to generate the new color correction data and update the color correction data with the new color correction data, and corrects the gradation of the image contained in the image data using the new color correction data. When the instruction does not contain the first instruction and also when the given condition is not satisfied, the control unit corrects the gradation of the image contained in the image data using the existing color correction data stored in the nonvolatile memory.
