One of the major mechanical shortfalls associated with the organic belted photoreceptors (P/R) is the dynamic fatigue small molecule transport layer cracking over small diameter belt module rollers (e-g. 19 mm roller) after extended P/R belt cycling. Under a machine function condition, the small molecule transport layer, being situated at the top of the P/R belt, is repeatedly subjected to the maximum bending stress each time it flexes over a belt module roller. Consequently, this fatigue bending stress leads to premature small molecule transport layer cracking and shortens its service life.
