  • Patent number: 6871040
    Abstract: Provided is an image forming process which can effectively suppress the occurrence of separation electrification between a belt surface layer and an image-receiving layer of an electrophotographic image-receiving sheet at a cooling and separation unit, prevent dust from adsorbing to charges at each surface thereof, and print high quality images having near-photographic quality, in which a belt-fixing smoothing device having a heating and pressuring member, a belt member, a cooling device, and a cooling and separating unit is used to conduct fixing treatment to an electrophotographic image-receiving sheet. In this case, a surface resistivity (SR1) of one side of the image-receiving sheet on which an image is formed satisfies the formula 1.0×109 ?/cm2?SR1?1.0×1014 ?/cm2, and a surface resistivity (SR2) of one side of the belt member which becomes in contact with the image satisfies the formula SR2?1.0×1014 ?/cm2.

  • Patent number: 6049674
    Abstract: A self-photography apparatus has an imaging device for picking up an image signal representing a facial image of a human object, a determination device for determining the size of face of the human object. In accordance with the determined face size, the magnification of the image is adjusted so as to make the facial image have a predetermined size in a photograph. The determination device is comprised of a monitor display displaying a video facial image of the human object and indices as the scale of the face size. The magnification of image is changed by manually or automatically changing the object distance or mechanically changing the focal length of a taking lens device. When making a photograph by video printing, the determination device may be a controller determining the face size on the basis of the image signal, an image magnification conversion circuit converts the magnification of image in accordance with the face size determined by the controller.
