<p>A Multi-Functional Peripheral (MFP) comprising: a registration adjuster for making a registration adjustment by adjusting an image forming position of each color; a detector (110) for detecting an intensity of a vibration; a transmitter (109) for transmitting the image data to another apparatus via a network (120); and a controller (101) for (i) interrupting an image formation if the intensity of the vibration is judged to be larger than a first threshold, (ii) instructing the transmitter to transmit the image data of the interrupted image formation to the another apparatus if the intensity of the vibration is judged to be larger than a second threshold that is larger than the first threshold, and (iii)after the vibration has ceased, instructing the registration adjuster to make the registration adjustment and then restarting the interrupted image formation.
