Abstract
The invention provides a photoconductive switching element used for light switching of a functional element driven by an AC electric field or AC current which are highly functional and inexpensive and provides a device in which such a photoconductive switching element and a functional element such as a liquid display element are combined and incorporated, and an apparatus, a recording apparatus, and a recording method which are provided with the above-mentioned device. The photoconductive switching element has at least a light transmissible electrode layer, a charge generation layer, a charge transfer layer, and a charge generation layer laminated in this order on a light transmissible substrate. The photoconductive switching element is combined with a functional element to form a device of the present invention, and the device is incorporated in an apparatus or a recording apparatus to fabricate an apparatus or a recording apparatus respectively of the present invention. In the recording method of the present invention, such a recording apparatus is used.
