| Zusammenfassung: | A conductive roller includes a supporting member and a conductive elastic foam layer disposed on the supporting member. In a spectrum of amplitude (μm) vs. period (μm) obtained by subjecting a roughness waveform of the outer circumferential surface of the conductive elastic foam layer in an axial direction to fast Fourier transformation, the integrated value St of the amplitude within a period range of 100 μm or more and 300 μm or less is 455 μm or less. |
