Title (EN) ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC APPARATUS
(FR) ÉLÉMENT PHOTOSENSIBLE ÉLECTROPHOTOGRAPHIQUE, CARTOUCHE DE TRAITEMENT ET APPAREIL ÉLECTROPHOTOGRAPHIQUE
Abstract:
(EN) In an electrophotographic photosensitive member, a circumferential surface has concave portions that are independent one another; each of the concave portions has an opening, a contour of the opening has an apex having an angle a of more than 0° and 90° or less on at least an upstream side of a rotational direction of the electrophotographic photosensitive member, and has a largest width in an axial direction of the electrophotographic photosensitive member of 20 μκι or more and 80 μπι or less, a width of the contour in the axial direction of the electrophotographic photosensitive member decreasing from a portion having the largest width toward the apex, when viewing each of the concave portions in the axial direction, each of the concave portions has a depth that decreases from a deepest point of each of the concave portions toward the apex.
(FR) Dans un élément photosensible électrophotographique selon l'invention, une surface circonférentielle possède des parties concaves qui sont indépendantes les unes des autres ; chacune des parties concaves présente une ouverture, un contour de l'ouverture présente un sommet ayant un angle a supérieur à 0° et inférieur ou égal 90° sur au moins un côté amont d'une direction de rotation de l'élément photosensible électrophotographique, et présente une plus grande largeur dans une direction axiale de l'élément photosensible électrophotographique supérieure ou égale à 20 μm et inférieure ou égale à 80 µm, une largeur du contour dans la direction axiale de l'élément photosensible électrophotographique diminuant depuis une partie ayant la plus grande largeur vers le sommet, lorsque l'on regarde chacune des parties concaves dans la direction axiale, chacune des parties concaves présente une profondeur qui diminue depuis un point le plus profond de chacune des parties concaves vers le sommet.
