Abstract
(EN) To provide a member for electrophotography, which is further suppressed in adhesion of a toner or an external additive and does not easily cause defects in electrophotographic images, while having uniform electrical conductivity. A member for electrophotography, which comprises a conductive base and a conductive resin layer that serves as a surface layer. This member for electrophotography is characterized in that: the resin layer contains conductive particles and a binder resin; and the binder resin is a polymer that is obtained by crosslinking a polymer chain, which has at least one unit that is selected from the group consisting of units represented by formula (1) and formula (2) and at least one unit that is selected from the group consisting of units represented by formula (3) and formula (4), by means of at least one organopolysiloxane chain that is selected from the group consisting of structures represented by formula (5) and formula (6).
(FR) La présente invention concerne la fourniture d'un élément pour électrophotographie, dont on a réduit encore l'adhérence d'un toner ou d'un additif extérieur et qui ne provoque pas facilement de défauts dans des images électrophotographiques, tout en présentant une conductivité électrique uniforme. L'invention concerne également un élément pour électrophotographie, qui comprend une base conductrice et une couche de résine conductrice qui sert de couche de surface. Cet élément pour électrophotographie est caractérisé en ce que : la couche de résine contient des particules conductrices et une résine servant de liant; et la résine servant de liant est un polymère qui est obtenu par réticulation d'une chaîne polymère, qui comporte au moins un motif qui est choisi dans le groupe constitué des motifs représentés par la formule (1) et la formule (2) et au moins un motif qui est choisi dans le groupe constitué des motifs représentés par la formule (3) et la formule (4), au moyen d'au moins une chaîne organopolysiloxane qui est choisie dans le groupe constitué des structures représentées par la formule (5) et la formule (6).
