摘要： A heat roller for a fixing device included in an image forming apparatus has an insulation layer and a conductive layer sequentially formed on the inner periphery thereof. To form each of the insulation layer and conductive layer, a spray gun is inserted into the heat roller. Subsequently, paint, which is a liquid for forming the insulation layer or the conductive layer, is fed under pressure to the spray gun. The paint is radially jetted via the holes of the spray gun and evenly deposits on the inner surface of the heat roller. In this condition, the spray gun is moved in a preselected direction in order to coat the entire inner periphery of the heat roller. After the insulation layer has been formed and then sintered, the conductive layer is formed on the insulation layer and then sintered. The two layers can be formed in a short period of time and provides the heat roller with high quality at low cost. A method of producing the heat roller is also disclosed.
