摘要：
A roller for electrophotography including a mandrel and an elastic layer on the mandrel is provided. The elastic layer contains a hollow particle in a region from the surface of the elastic layer to a depth of 100 μm. A cross-section of the hollow particle intersected by a first plane and a cross-section of the hollow particle intersected by a second plane each have a ratio of the length of the long axis to the length of the short axis of 1.2 or more and 1.9 or less.
