Abstract
The presently disclosed embodiments are directed to layer(s) that are useful in imaging apparatus members and components, for use in electrophotography, including digital, apparatuses. More particularly, the present embodiments provide the negatively charged electrophotographic imaging members with a novel cross-linked charge blocking undercoat layer, which is created to comprise of a binary composition of melamine and formaldehyde or a triple composition consisting of a hydroxyl functional acrylic polyol binder and a methylolation of melamine-formaldehyde, and methods for making the same. The charge blocking layer provides stabilized cyclic photo-electrical properties, enhanced mechanical adhesion bonding, and improved copy print out quality for service life extension.
