なる等の欠点がある。The blending ratio of the epoxy compound in the thermosetting resin is preferably selected to be 5 to 30% by weight. If the blending ratio is less than 5% by weight, the range of conductivity will not expand, but if the blending ratio is 5% by weight or more, the range of conductivity will expand. A synergistic relationship was observed. In addition, if the blending ratio exceeds 30% by weight, resin blur occurs during coating and drying, making it difficult to form a uniform coating, prolonging the curing time, reducing productivity, and increasing the strength of the finished coating. There are disadvantages such as weakening.

The blending ratio of resol type phenol formaldehyde resin in the thermosetting resin is 70 to 9
It is preferable to select 5% by weight, and the blending ratio is 70% by weight.
If the amount is less than 70% by weight, it will take a long time to cure, resulting in poor productivity and it will not be possible to form a strong coating upon completion, but if it is 70% by weight or more, a strong coating after curing can be formed.

It has excellent properties and has a synergistic effect with the cationic semi-insulating resin that expands the range of conductivity. Furthermore, if the mixing ratio R is 0.6 or more, resin sag occurs during coating and drying, and the curing reaction between the epoxy compound and the resol type phenol formaldehyde resin is inhibited.

50 parts by weight IC: A composition with a ratio of 75 parts by weight, both sides were adjusted to a solid content and viscosity suitable for coating with methyl cellosolve, and the curing conditions were air drying for 1 hour → 40°C x 30 Minutes → 90℃×30 minutes→150℃×
Heating was performed for 30 minutes → 170° C. for 1 hour, and the cured product was tested for volume resistivity, hardness, adhesion, and resin sag resistance during curing. As shown in Table 1, Examples 1 and 2
, 3.4.5 obtained good results in volume resistivity, hardness, adhesion, and resin sag.

するものである。[9 lines below] (c) Effect of the invention As can be seen from the above examples and comparative examples, the semi-insulating resin composition for transfer rollers of the present invention can electrostatically adsorb toner when used in a transfer roller. The amount of electrostatic adsorption of toner can be set to a volume resistivity that can be adjusted, and there is no resin sag during curing, and coating drying properties are good, resulting in a uniform coating film.
It has appropriate hardness and excellent durability as a transfer roller.
