An image formation apparatus includes a flash memory as an image data buffer, and a control section, where data writing to each memory block of the flash memory is controlled by using wear leveling. The control section predicts whether writing of a certain amount of image data such that the amount of image data to be written into the flash memory in a predetermined period exceeds a predetermined value, will occur, and on predicting that the writing of the certain amount of image data will occur, restricting an input of image data and/or a speed of buffering the image data, to reduce the amount of image data to be written into the flash memory in the predetermined period.
