A toner supply roll free from occurrence of an imaging failure. The toner supply roll comprises a shaft (1) and a urethane foam layer (2) provided on an outer peripheral surface of the shaft (1), wherein when the urethane foam layer is compressed to a depth of 1 mm from an outermost surface thereof during compression thereof to a depth of 2 mm, a stress F₀ occurs in the urethane foam layer and when the urethane foam layer is decompressed to a depth of 1 mm after the compression thereof to a depth of 2 mm, a stress F₁ occurs in the urethane foam layer, the urethane foam layer satisfies a relation represented by the following expression (1) at a temperature of 233 C. at a humidity of 5010%:

the stresses F₁ and F₀ being expressed by a unit of Pa.
