Conductive support, electrophotographic photoreceptor, and process cartridge

The invention provides a conductive support, an electrophotographic photoreceptor, and a process cartridge. The conductive support is formed of a bottomless hollow cylindrical member being made of metal and having a thickness t of equal to or less than 0.5 mm, the conductive support including: a chamfer portion on an outer peripheral surface side of at least one end of the conductive support overan entire circumferential direction, wherein the chamfer portion has a chamfer angle a of equal to or greater than 10 degrees and less than 30 degrees with respect to the outer peripheral surface, anda chamfer width b equal to or greater than 0.05 mm in an end surface, and wherein as end surface width c is equal to or greater than 0.1 mm in the end surface including the chamfer portion. 本发明提供种导电性支持体、电子照相感光体以及处理盒。导电性支持体由无底中空圆筒形部件形成，此无底中空圆筒形部件由金属制成并且具有等于或小于0.5mm的厚度t，所述导电性支持体包括：所述导电性支持体的至少端的外周表面侧上的在整个圆周方向上的斜切部，其中，所述斜切部具有相对于所述外周表面等于或大于10°并且小于30°的斜切角a以及端部表面中的等于或大于0.05mm的斜切宽度b，并且其中，在包括所述斜切部的所述端部表面中端部表面宽度c等于或大于0.1mm。
