    Abstract: An electrophotographic photosensitive member is constituted by disposing a photosensitive layer including a charge generation layer and a charge transport layer on an electroconductive support. The charge transport layer has a thickness of at most 12 .mu.m and is formed by dispersing therein particles having a particle size of 1-3 .mu.m at a density of 1.times.10.sup.4 -2.times.10.sup.5 particles/mm.sup.2. The charge transport layer and the particles described above provides a difference in refractive index of at least 0.10. The photosensitive member is effective in providing good images free from black spots and interference fringes and with a good gradation-reproducing characteristic when used as a structural member of a process cartridge and an image forming apparatus.

    Abstract: A digital cross connect system includes reception interface parts for converting an input line signal into a VT signal having a VT frame format in conformance with synchronous optical network (SONET) standards, a switching part for cross connecting the VT signal received from the reception interface parts, and transmission interface parts for converting the cross connected VT signal received from the switching parts into a line signal. The reception interface part inserts a frame synchronizing signal within a reserved path overhead part of the VT signal, and the transmission interface part achieves frame synchronization of the VT signal in response to the frame synchronizing signal.
