摘要:
An optical information recording medium comprising a substrate and a recording layer superimposed on said substrate, said recording layer comprising a reflective layer in which metal particles with a particle diameter of 1500.ANG. or less have been distributed closely and a light absorptive layer in which metal compounds and a very small amount of metal particles with a particle diameter of 200-2000.ANG. have been dispersed unformly or substantially uniformly in the volume ratio of 1-30% in a resin.
摘要:
A device included in an image forming apparatus for removing a substance that disfigures an image. The device includes an adsorbent support that supports an adsorbent. The absorbent has a molecular structure including voids that have a diameter great enough to pass molecules of the disfiguring substance which is deposited on the surface of an image carrier and contain water.
摘要:
A device for removing a film-like image forming substance from a recording medium for thereby regenerating the medium. A supply section supplies to the medium a water-containing removal accelerating liquid which causes a swelling layer of the medium to swell more than the substance provided on the medium. A separating section presses, after the liquid has been supplied to the medium, a separating member against the medium with or without heating to thereby transfer the substance from the medium to the separating member and thereby regenerates the medium. A cleaning section removes impurities deposited on the separating member.

In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, an unstabilizing agent is provided to the image holding member. An attaching state between the image forming substance and the image holding member stably attaching the image forming substance on a surface thereof is changed to an unstable state by the unstabilizing agent. The image forming substance is separated and removed from the image holding member by making a separating member come in close contact with the image forming substance on the image holding member having the provided unstabilizing agent. A processing situation mark showing a processing situation of removal of the image forming substance is formed in the image holding member. The processing situation mark can be removed from the image holding member by the image forming substance removing processing.

In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, a CCD sensor detects an unremoved image formed by a stamp, additional writing, etc. and left on the transfer paper sheet after toner separating processing is performed with respect to the transfer paper sheet by a liquid-providing toner-separating unit. A discriminating mark such as a punch, a mark o, etc. is additionally provided to the transfer paper sheet having the detected unremoved image by a discriminating mark providing unit. The transfer paper sheet having the discriminating mark is automatically sorted by a sorting unit and is discharged onto a paper discharging tray. The toner removing apparatus may have an unrecognizing device for blotting the unremoved image such as a seal print, a signature, etc. on the transfer paper sheet. The unrecognizing device may coat the unremoved image with ink having the same color as the unremoved image, or may punch the unremoved image. Thus, it is possible to prevent the transfer paper sheet having the unremoved image from being used or thrown away in error and prevent the unremoved image from being abused in advance.

In a method of and an apparatus for regenerating an image support from a used image-bearing support which bears thereon hydrophobic images formed of thermofusible or heat-softening ink, a plurality of image releasing members are used for removing the hydrophobic images from the used image-bearing support. Specifically, at least one of the image releasing members has a first portion which is able to adhere to the hydrophobic images and a second portion which is unable to adhere to the hydrophobic images, and the image releasing members are arranged in series in order of size of the first portion from small to large along a feeding direction of the used image support. Accordingly, the image releasing members are allowed to adhere to the hydrophobic images in order of size of the first portion from small to large so that the hydrophobic images are removed from the used image support effectively. It is preferable that the image releasing member finally allowed to adhere to the hydrophobic images is a solid image releasing member.
摘要:
A method of recycling an image-deposited recording material having a surface portion which swells in contact with water and bears thereon deposited images containing an image-constituting material, include the steps of: (a) applying a water-containing image removal promoting liquid to the image-deposited surface portion of the recording material, (b) bringing an image release member into contact with the image-deposited surface portion of the recording material to transfer the images to the image release member to remove the images from the image-deposited recording material, and (c) applying heat to the image-deposited recording material at least after the step (a), with substantially retaining the water component of the image removal promoting liquid in the image-deposited surface portion. In addition, there is disclosed an apparatus for recycling the above-mentioned image-deposited recording material comprising an image removal promoting liquid application means, a water evaporation preventing means, a heat-application means for heating the image-deposited recording material in such a manner that the water component of the image removal promoting liquid is retained in the surface portion, and an image release means.
摘要:
A method for preparing an electrophotographic element wherein in the formation of a co-crystalline complex photosensitive layer a conducting substrate or another photosensitive layer is over-coated with a solution consisting essentially of a pyrylium dye and an electric insulating polymer and dried at least two times respectively.
摘要:
An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.
