摘要： In an image formation method of an image formation apparatus for correcting uneven image formation on the basis of vibration property information corresponding to an operation sequence in image formation, vibration property information corresponding to a plurality of operation sequences are stored in a storage device. The uneven image formation is corrected on the basis of vibration property information corresponding to an operation sequence selected from the storage device. Vibration property information generated by driving a movable member is measured when the selected operation sequence is being executed while correcting the uneven image formation. It is determined whether the measured vibration property information is similar to the vibration property information selected from the storage device. The vibration property information stored in the storage device is rewrite-controlled in accordance with the measurement result or the determination result.
