An object is to provide an SOI substrate with excellent characteristics even in the case where a single crystal semiconductor substrate having crystal defects is used. Upon the reception of an image forming signal at the image forming apparatus, the first and the second developer carrying members are rotated before the first latent image on the image bearing member is developed. The water supply system can be sent to a deaerator stripper or can be heated using a heat exchanger. However, if the supply voltage for the analog multiplexor is above or equal to the threshold voltage, then the method includes the step of transmitting at least one input signal coupled to the analog multiplexor to the output of the analog multiplexor. In another aspect, the known logical locations are stored in metadata. The image capturing apparatus has a plurality of display items respectively associated with the image blurring correction modes, and displays the display item corresponding to the image blurring correction mode under execution on a display screen.
