An electrophotographic imaging member comprising
- a supporting substrate having an electrically conductive surface,
- a hole blocking layer,
- an optional adhesive layer,
- a charge generating layer,
- a charge transport layer,
- an optional anticurl back coating,
- a ground strip layer and
- an optional overcoating layer,
- at least one of said charge transport layer, anticurl back coating, ground strip layer and overcoating layer comprising silica particle clusters homogeneously dispersed in a film forming matrix, said silica particle clusters consisting essentially of spherically shaped amorphous primary silicon dioxide particles permanently bonded or fused to each other.
An electrophotographic imaging member comprising a charge transport layer comprising
- a thermoplastic film forming binder matrix,
- charge transport molecules and
- a homogeneous dispersion of silica particle clusters in said film forming binder matrix, said silica particle clusters consisting essentially of spherically shaped amorphous primary silicon dioxide particles permanently bonded or fused to each other.
