Abstract:
Provided is a development roller which is capable of improving a black solid density and a 2-dot density simultaneously to form a satisfactory image with excellent contrast and thin line reproducibility. A development roller includes a roller body that contains a tubular inner layer consisting of an elastic material and an outer layer consisting of an elastic material, a roller resistance value R 1  (Ω, an applied voltage of 400 V) in a state when there is only the inner layer satisfies formula (1): 6.5≤log  R 1 ≤9.5  (1), and a volume resistivity R 2  (Ω·cm, an applied voltage of 400 V) in a state when there is only the outer layer satisfies formula (2): log  R 2 ≤9.0  (2).

Claim (Index 2):
The development roller according to  claim 1 , wherein the inner layer consists of a cross-linked product of a rubber composition containing a diene rubber, an ethylene propylene diene rubber, and carbon black.
