特徴とする。[Summary of the Invention] 1 That is, the ethylene/7 [J pylene rubber roller of the present invention] is a base rubber made of ethylene/propylene rubber in which the ratio of ethylene to propylene is a molar ratio C (hereinafter the same) of 70:30 to 45:55. A composition consisting of 100 parts by weight, 40 to 120 parts by weight of an inorganic filler excluding carbonates and hydroxides, and appropriate softeners, organic peroxides, and crosslinking coagents was placed on a D-ru core shelf. It is coated and cross-linked by heating to become -C,
It is characterized by its ability to withstand LJISA type hardness of 50 or less.

Gugir. Note that the addition of carbonates such as calcium carbonate and magnesium carbonate or hydroxides such as aluminum hydroxide is not preferable since it may reduce the body image carrier property. The appropriate amount of the inorganic filler to be added to 100 parts by weight of the base rubber is 40 to 120 parts by weight, preferably 50 to 80 parts by weight. 40 parts by weight W
4'c has a large shrinkage during processing or extrusion, making it difficult to extrude, and if it exceeds 120 yen, the developer resistance decreases.

Naphthene-based process oils, phthalic acid-based oils, and sebacic acid-based oils tend to bleed easily and are not preferred. The amount of process oil to be blended is suitably used within a range that makes the hardness of the rubber 50 or less, but a suitable amount is 5 to 70 parts by weight per 100 parts by weight of the base rubber. If it is less than 5 parts by weight, the processability will be poor, and if it exceeds 70 parts by weight, the unvulcanized rubber will be too sticky and difficult to process. In addition to the process oil, a small amount of petrolatum, microcrystalline wax, sudearic acid, etc. may also be used.
