Abstract
There are provided an organic polymer composition having an antistatic property, and a molding product and a fixing device using the same. The organic polymer composition comprises at least an organic polymer and porous inorganic fine powder carrying a liquid antistatic agent dispersed in the organic polymer; the porous inorganic fine powder having an oil absorption of 100 ml/100 g or larger before it carries the liquid antistatic agent.
Claims25
A fixing device, comprising at least a pair of rollers between which a toner image-supporting material carrying an unfixed toner image is passed under heating and pressure to fix the toner image to the toner image supporting material;
- wherein at least one of said pair of rollers comprises an elastic roller including an elastic layer which is obtained by thermally molding a mixture comprising at least an organic polymer and porous inorganic fine powder carrying a liquid antistatic agent;
- said porous inorganic fine powder being dispersed in the organic polymer;
- said porous inorganic fine powder having an oil absorption of 100 ml/100 g or larger before it carries the liquid antistatic agent.
