Document Type and Number:
WIPO Patent Application WO/2018/029996
Kind Code:
A1
Abstract:
To provide an electroconductive roll (R) with which it is possible to suppress toner stress in a low-temperature, low-humidity environment. An electroconductive roll (R) for an electrophotographic device, the electroconductive roll (R) having a surface layer (1). In a surface hardness histogram (10) of the surface layer (1) measured using an atomic force microscope (AFM), the surface hardness (H) at the top peak (P) is in the range of 10-55 MPa, and the area ratio (S) of the histogram portion corresponding to a surface hardness of 45 MPa or below in relation to the entire histogram is 65% or above.
