Tubular member, tubular member unit, intermediate transfer member, and image forming apparatus

摘要

A tubular member includes a resin layer containing a thermoplastic resin and a conductive material, and the resin layer forming a sea part in which the thermoplastic resin becomes a matrix phase, wherein an area ratio of the sea part to a portion in a range of 5 μm respectively to a front surface portion side and a rear surface portion side with a central portion of the resin layer in a thickness direction as a center is greater by 3% to 15% than a greater area ratio between an area ratio of the sea part to a portion in a range of 10 μm from a front surface portion of the resin layer in the thickness direction and an area ratio of the sea part to a portion in a range of 10 μm from a rear surface portion in the thickness direction.

主权项

1. A tubular member comprising:
a resin layer containing a thermoplastic resin and a conductive material, and the resin layer comprising:
a sea part in which the thermoplastic resin has a matrix phase,a front surface portion;a rear surface portion;a center between the front surface portion and a rear surface portion; and
a central portion measured from (A) 5 μm from the center towards the front surface portion in a thickness direction to (B) 5 μm from the center towards the rear surface portion in the thickness direction; and wherein a first area ratio of the sea part between (1) an area of the sea part to (2) an area of the central portion is greater by 3% to 15% than the larger ratio of:
a second area ratio of (1) the area of the sea part to (2) an area of a portion of the resin layer measured as 10 μm of from the front surface portion in the thickness direction, ora third area ratio of (1) the area of the sea part to (2) an area of a portion of the resin layer measured as 10 μm of from the rear surface portion in the thickness direction, andwherein the first, second and third ratios are different from each other.
