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.

摘要： A switching power supply unit is capable of performing zero-voltage switching in the entire load region to reduce switching loss and noise and improve the voltage transmission efficiency. The switching power supply unit has a main switching device, and an auxiliary switching device for controlling resonance so as to prevent power loss accompanying a switching action of the main switching device. A control circuit varies the OFF period, during which the main switching device and the auxiliary switching device are OFF simultaneously, according to power consumption by a load on an apparatus in which the switching power supply unit is installed.
