    摘要: An image forming apparatus includes a developing device including a developing roller to bear a developing agent to develop a latent image formed on an image bearing member, a cooling device to reduce an internal temperature of the image forming apparatus, a controller to calculate a travel distance of the developing roller to control the cooling device, and a memory unit to store the total travel distance of the developing roller. The controller calculates the total travel distance of the developing roller every Y minutes in the last X minutes, and a difference between the latest total travel distance of the developing roller and the total travel distance stored Z minutes ago by the memory unit to obtain the total travel distance during Z minutes and operate the cooling device for W minutes after image forming operation where the difference is equal to or greater than a threshold value M.

    摘要: A fixing apparatus includes a fixing member to be heated and a pressure-contacting member for pressure contacting the fixing member. The fixing apparatus directs and conveys a recording member through a nip formed between the fixing member and pressure applying member in such a manner that a toner image carried on a recording member contacts the fixing member in order to be fixed thereto with heat and pressure. The fixing apparatus is configured to direct a tip margin of the recording member toward the pressure applying member across a virtual linear extension line drawn from a downstream end to upstream end of the nip when only the tip margin exits from the nip. A fixing member side separation device may be separately provided from the surface of the fixing apparatus so as to separate the recording member exiting from the nip. A gap formed between the downstream end of the nip and the tip of the fixing member side separation device is set smaller than the width of the tip margin.

    摘要: An image forming apparatus includes an image carrier, a charging device configured to uniformly charge a surface of the image carrier with a charging member applied with a bias of a first polarity (e.g. a negative polarity) for charging. A latent image forming device forms a latent image on the surface of the image carrier uniformly charged. A developing device develops a latent image by depositing toner grains of the first polarity on the latent image to thereby form a corresponding toner image. A transferring device forms an electric field between the image carrier and a moving member that serves as a movable contact with the image carrier to thereby transfer the toner image from the surface of the image carrier to the moving member or to a recording member nipped between the image carrier and the moving member. A polarity controlling device sets residual toner to a second polarity (e.g. a positive polarity) opposite to the first polarity, before the residual toner left on the image carrier by the transferring device is conveyed to a corresponding position to the charging member.
