Abstract
An image forming method, which includes transferring an image of toner on an image carrying member to a recording medium, and fixing the image transferred to the recording medium, includes: smoothening a surface of the image transferred to the recording medium; and penetrating the image into the recording medium without contact on the surface of the image on the recording medium. The penetrating is a final process of the fixing.
Claims14
An image forming method including:
- transferring an image of toner on an image carrying member to a recording medium;
- and
- fixing the image transferred to the recording medium, comprising:
- contact fixing a surface of the image after the image is transferred to the recording medium using an image contact fixing unit wherein the image contact fixing unit contacts the surface of the image on the recording medium, so that a smoothness which corresponds to a surface roughness of the image with respect to a surface roughness of the recording medium is 2 or less;
- and
- non-contact fixing the image into the recording medium without contact on the surface of the image on the recording medium,
- wherein the non-contact fixing is a final process of the fixing, and
- a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.

An image forming method comprising:
- contact fixing by transferring an image with a toner having a shape factor of 130 or less and an average particle diameter of 7 μm or less formed on an image carrying member to a recording medium;
- contact fixing a surface of the image after the image is transferred to the recording medium using an image contact fixing unit wherein the image contact fixing unit contacts the surface of the image on the recording medium;
- and
- non-contact fixing the image into the recording medium without contact on the surface of the image on the recording medium, wherein a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.
1 more element
An image forming apparatus comprising:
- a transferring device that transfers an image of a toner on an image carrying member to a recording medium;
- and
- a fixing device that fixes the image transferred to the recording medium, wherein the fixing device comprises:
- an image contact fixing unit that smoothens a surface of the image after the image is transferred to the recording medium wherein the image contact fixing unit contacts the surface of the image on the recording medium, and
- an image non-contact fixing unit, constituted as a final stage unit of the fixing device, that penetrates the image having been subjected to the image contact fixing unit, into the recording medium without contact on the surface of the image on the recording medium, wherein
- a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.
3 more elements
An image forming apparatus including
- a transferring device for transferring an image of a toner on an image carrying member to a recording medium;
- and
- a fixing device for fixing the image transferred to the recording medium, comprising:
- an image contact fixing unit, disposed upstream of the fixing device, that smoothens a surface of the image after the image is transferred to the recording medium wherein the image contact fixing unit contacts the surface of the image on the recording medium;
- and
- an image non-contact fixing unit, constituted as a final stage unit of the fixing device, that penetrates the image having been subjected to the image contact fixing unit, into the recording medium without contact on the surface of the image on the recording medium, wherein
- a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.
4 more elements
A fixing device for fixing an image of a toner transferred from an image carrying member to a recording medium, the fixing device comprising:
- an image contact fixing unit that smoothens a surface of the image after the image is transferred to the recording medium wherein the image contact fixing unit contacts the surface of the image on the recording medium, and
- an image non-contact fixing unit, constituted as a final stage unit of the fixing device, that penetrates the image having been subjected to the image contact fixing unit, into the recording medium without contact on the surface of the image on the recording medium, wherein
- a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.
An image forming method comprising:
- transferring an image of a toner on an image carrying member to a recording medium;
- and
- fixing the image transferred to the recording medium by first contact fixing a surface of the image after the image is transferred to the recording medium using an image contact fixing unit wherein the image contact fixing unit contacts the surface of the image on the recording medium and subsequently non-contact fixing the image into the recording medium without contact on the surface of the image on the recording medium,
- wherein
- a cross-sectional shape of a surface of an image on the recording medium after subjecting to the fixing follows a cross-sectional shape of a surface of the recording medium, and
- a transporting speed of the recording medium during the non-contact fixing of the image is smaller than a transporting speed of the recording medium during the contact fixing.
