  • Patent number: 9465337
    Abstract: An image forming apparatus, upon receipt of an image formation request, controls execution of a second preparatory operation that needs to be performed so that the image forming unit is capable of performing image formation and, independently of the image formation request, controls execution of a first preparatory operation for preparation for the image forming unit before the second preparatory operation. The first and second preparatory operations are accompanied by driving of a photosensitive body. Further, the image forming apparatus, when the image formation request is received by the reception unit before completion of the first preparatory operation, determines whether the second preparatory operation is to be performed after the first preparatory operation without stopping driving of the photosensitive body or after the first preparatory operation by stopping driving of the photosensitive body, in accordance with content of image formation performed in response to the image formation request.

  • Publication number: 20160240582
    Abstract: The present disclosure relates to a solid-state imaging element in which the cost reduction of a curved imaging element can be achieved, a method for manufacturing the solid-state imaging element, and an electronic apparatus. A curvature base is formed so as to be curved in a concave shape at a center leaving a small edge. The curvature base is divided into five portions of an element disposition portion and four peripheral portions. This element disposition portion is formed in a porous state. A pore (air bubble) in the porous state is smaller than a pixel size. A porous material such as a ceramic-based material, a metal-based material, or a resin-based material can be used as the porous material, for example. The present disclosure can be applied to a CMOS solid-state imaging element to be used for an imaging device, for example.
