    摘要： In an image forming apparatus having a charging member for charging a photoconductive element in the form of a drum or a belt in contact therewith, a cleaning member cleans the surface of a charge roller contacting the photoconductive element. The cleaning member is usually spaced apart from the surface of the charge roller, but the former is caused to contact the latter only for a predetermined period of time at predetermined intervals. This frees the charge roller from excessive cleaning due to the cleaning member and, therefore, obviates defective images. The time for causing the cleaning member to contact the charge roller may be changed on the basis of the degree of contamination of the charge roller in order to cope with accidental smears brought about on the charge roller.

    摘要： An image forming apparatus includes a photosensitive body. A charge member is held in contact with the photosensitive body and charges the photosensitive body by applying a voltage thereto. An exposure device exposes a surface of the photosensitive body charged by the charge member and forms an electrostatic latent image. A developing device attaches toner to the electrostatic latent image on the photosensitive body and visualizes the electrostatic latent image. Further, a particle diameter of fine powder which is the toner used in the developing device is equal to or less than 3 .mu.m, and a containing rate of the fine powder is equal to or less than 5%. Further, an angle of spatula of the toner used in the developing device may be at least 25 degrees. A cohesiveness of the toner may also be at least 9%.

    摘要： An image forming apparatus includes a contact charging member which contacts a surface of an image carrier member in order to charge the surface of the image carrier member, and a cleaning member which contacts and slides on a surface of the contact charging member in order to clean the surface of the contact charging member. The image forming apparatus performs a function in such a way that after an electrostatic latent image is produced on the image carrier member which is in a charged state, toner powder is supplied to the image carrier member by a developing device in order to make the electrostatic latent image visible and then a visualized image is transferred to a transfer member. In the image forming apparatus, a maximum height of concavities and convexities formed on the surface of the contact charging member is equal to or less than an average particle diameter of the toner powder supplied by the developing device.

    摘要： A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc. Thereafter, the transfer paper sheet is discharged onto a paper discharging tray. Accordingly, it is possible to provide a method and an apparatus for regenerating and reusing the transfer paper sheet by removing the toner therefrom without damaging paper fibers.

    摘要： In a method for repeatedly using an image holding member such as a sheet of paper, toner for an electronic photograph is constructed such that a maximum value of viscoelasticity of the toner shown by tan .delta. is equal to or smaller than 3 in the range of a heating temperature when the toner is heated and fixed to the image holding member. Such toner has sufficient elastic or cohesive force. Accordingly, when the toner is heated and fixed to the paper sheet, no excessive adhesive force is caused to such an extent that paper fibers of the paper sheet eat into the toner attached to the paper sheet. Accordingly, after an aqueous solution including a surfactant is supplied to the paper sheet by a liquid supplying unit, the toner is softened by heat from heating rollers so that the toner is attached to a surface of an offset belt. When the toner attached to the surface of the offset belt is separated from the paper sheet, the toner can be completely removed from the paper sheet without damaging paper fibers on a surface of the paper sheet.

    摘要： This invention provides a method for using paper repeatedly by flaking and removing an image from the paper, even if the image has been touched up on the paper with handwriting, and a preferable printing tool used in the method. The method includes the steps of touching up the image on the paper with the printing tool containing a main component of a colored thermoplastic resin particle and being formed into a stick shape by solidifying the resin particle alone or with binder resin sticking to the resin particle. The image can be formed on the paper with a liquid-applying type of printing tool having a liquid container containing a resin dispersion liquid being formed by dispersing the resin particle in a solvent. Regenerating of the paper by removing the touched-up image from the paper comprises the steps of wetting the paper through a treatment liquid such as water, and while heating the resin particle of the image, adhering the resin particle to a flaking member having a greater adherent force to the resin particle than the adherent force between the resin particle and a surface of the paper so as to flake and remove the resin particle from the surface of the paper.
