Abstract
A fixing apparatus includes a fixing device configured to, by allowing a sheet having a developing agent image on it to pass between a heating roller and a pressing roller set in contact with the heating roller, fix the developing agent image in which at least one of the heating roller and pressing roller is configured to have an inner elastic layer and a conductive layer formed on a surface side of the elastic layer and the elastic layer is bonded to the conductive layer by a heat-resistant adhesive having a heat-resistant temperature of over 200° C.

A fixing apparatus including a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image, wherein at least one of the heating and pressing rotation bodies has an elastic layer on an inner side and a conductive layer formed on a surface side of the elastic layer and wherein the elastic layer and conductive layer are bonded by a heat-resistant adhesive having a heat-resistant temperature of over 200° C.
A fixing apparatus comprising:
- a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image and wherein at least one of the heating and pressing rotation bodes is comprised of an elastic rotation body having a core member, an elastic layer formed on a surface of the core member and a conductive layer formed on a surface side of the elastic layer;
- a drive device configured to rotate the elastic rotation body by giving a rotation drive force to the core portion of the elastic rotation body;
- and
- a detection device configured to detect a difference between rotation speeds of the surface portion and the core portion at a rotation time of the elastic rotation body.
A fixing apparatus comprising:
- a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image, wherein any one of the heating and pressing rotation bodies is configured to have an elastic layer and a conductive layer formed on a surface side of the elastic layer and the other rotation body is configured to have an elastic layer on a surface and said one rotation body is configured to be rotationally driven with the rotation of said other rotation body;
- and
- a detection device configured to detect a slip between said one and other rotation bodies from a difference between the peripheral speeds of these rotation bodies.
A fixing apparatus comprising:
- a fixing device configured to set a pressing rotation body in contact with a heating rotation body and, by allowing a material to be fixed having a developing agent image to pass between the heating rotating body and the pressing rotation body, fix the developing agent image, the heating rotation body being configured to have an elastic layer and a conductive layer formed on a surface side of the elastic layer and the pressing rotation body being configured to have an elastic layer;
- a separation device abutted against the heating rotation body to allow the material to be fixed which is deposited on the heating rotation body to be separated from the heating rotation body;
- and
- an adjusting device configured to retain the separation device and have a positioning roller configured to abut against the heating rotation body and, by allowing the positioning roller to follow a surface displacement of the heating rotation body at a rotation time of the heating rotation body, adjust a distance between the separation device and the heating rotation body to be constant.
A fixing apparatus including a fixing device configured to set a pressing rotation body in contact with a heating rotation body and, by allowing a material to be fixed having a developing agent to pass between the heating rotation body and the pressing rotation body, fix the developing agent image, the heating rotation body being configured to have an elastic layer and the pressing rotation body being configured to have an elastic body and a conductive layer formed on a surface side of the elastic layer, wherein the thickness of the elastic layer of the pressing rotation body is thinner than that of the heating rotation body.
A fixing apparatus including a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image, wherein the heating rotation body and pressing rotation body are each configured to have an elastic layer and a conductive layer formed on a surface side of the elastic layer.
