| titleOfInvention | Toner supply roll |
| abstract | (57) [Summary] [PROBLEMS] To solve the problems of durability and foreign matters caused by tearing of a skin layer on a toner supply roll and a roll surface having high dimensional accuracy without causing fluff on the roll surface and unstable toner conveyance amount. Provided is a toner supply roll capable of suppressing breakage of an internal cell film and suppressing or eliminating a partial change in roll hardness due to entry of toner. SOLUTION: By foam molding of a polyurethane raw material, a closed cell foam structure is provided around a cored bar 32, the elongation at break is 100% or more, the tear strength is 0.4 kgf / cm or more, and the hardness is 350 g or less. Forming a soft polyurethane sponge layer 34 having a skin layer 36 forming a continuous smooth surface, and each cell 38 located immediately below the skin layer 36 is a cell central portion where the thickness of the skin layer 36 is reduced. Each of the cells 38 is independently opened to the outside by an opening 40 having an opening diameter of 100 to 800 μm formed at a corresponding portion, and furthermore, the entire area of the opening of these cells 38 occupies 20% or more of the surface of the skin layer 36. did. |
