The modifying powder is silk powder having an average particle diameter of 10 μm or less, oil absorption of 130 ml/100 g or less and particle diameter of 80 μm or less on the basis of dispersion degree evaluation with a grind gauge according to JIS K5400; or polysaccharide powder having an average particle diameter of 10 μm or less, and ink viscosity of less than 15 Pa·s or oil absorption of 85 ml/100 g or less. Such modifying powders can be obtained through a method comprising a first pulverization process for pulverizing a starting material for modifying material using a dry-type mechanical pulverizer such as a ball mill, and a second pulverization process for pulverizing the obtained pulverized product with a jet mill to fine particles having an average particle diameter of 10 μm or less, wherein pulverization treatment time in the first pulverization process is determined to be 40 hours or more.

A molded product comprising a resin material and/or elastomer containing modifying powder obtained by dry-pulverizing a starting material for modifying material, wherein:
A method for producing modifying powder wherein the modifying powder is obtained by pulverizing a starting material for modifying material, comprising:
A method for producing modifying powder wherein the modifying powder is obtained by pulverizing a starting material for modifying material comprising:
A liquid composition comprising modifying powder obtained by dry-pulverizing a starting material for modifying material, wherein the starting material for modifying material is polysaccharide, and the modifying powder has an average particle diameter of 10 μm or less and ink viscosity of less than 15 Pa·s.
A liquid composition comprising modifying powder obtained by pulverizing a starting material for modifying material, wherein the starting material for modifying material is polysaccharide, and the modifying powder has an average particle diameter of 10 μm or less and oil absorption of 85 ml/100 g or less.
A molded product comprising a resin material and/or elastomer containing modifying powder obtained by dry-pulverizing a staring material for modifying material, wherein the starting material for modifying material is polysaccharide, and the modifying powder has an average particle diameter of 10 μm or less and ink viscosity of less than 15 Pa·s.
A molded product comprising a resin material and/or elastomer containing modifying powder obtained by pulverizing a starting material for modifying material, wherein the starting material for modifying material is polysaccharide, and the modifying powder has an average particle diameter of 10 μm or less and oil absorption of 85 ml/100 g or less.
