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 1):
A development roller comprising a roller body, wherein the roller body comprises a tubular inner layer which consists of an elastic material and an outer layer which consists of an elastic material and is laminated on an outer periphery surface of the inner layer, a roller resistance value R 1  (\u03a9, an applied voltage of 400 V) in a state when there is only the inner layer satisfies formula (1):\n 6.5\u2264log  R 1 \u22649.5\u2003\u2003(1), and a volume resistivity R 2  (\u03a9\u00b7cm, an applied voltage of 400 V) in a state when there is only the outer layer satisfies formula (2):\n log  R 2 \u22649.0\u2003\u2003(2).
