Abstract

A packaged object includes an electrophotographic photosensitive member and a protective sheet. The electrophotographic photosensitive member is formed in a cylindrical shape. The protective sheet covers at least a portion of an outer circumferential surface of the electrophotographic photosensitive member so that a center position in an axis line direction is aligned with a center position of the electrophotographic photosensitive member in the axis line direction. Provided that a length of the electrophotographic photosensitive member in the axis line direction is denoted by L1 (mm) and a length of the protective sheet in the axis line direction is denoted by L2 (mm), a relationship expressed by Expression (1) below is established: L ⁢ 2 < L ⁢ 1 . ( 1 )
