Title:
電子写真機器用導電性ロール
Document Type and Number:
Japanese Patent JP7030019
Kind Code:
B2
Abstract:
Provided is a conductive roll for an electrophotographic machine. The conductive roll is a charging roll and includes a shaft body, and an elastic body layer formed on an outer periphery of the shaft body. The elastic body layer is a crosslinked body of a composition containing a diene-based polymer (a), a sulfur or peroxide crosslinking agent (b), carbon black (c), and a coupling agent (d). (c) has a specific surface area of 40 to 300 m2/g. (d) is a coupling agent having a NHR1 group and a SSO3H group, or a coupling agent having a NHR1 group and an ene structure (where R1 is H or a hydrocarbon group having 1 to 8 carbon atoms). The contents of (c) and (d) in the composition are respectively 10 to 45 parts by mass and 0.5 to 20 parts by mass with respect to 100 parts by mass of (a).
