| 摘要 |
The present embodiments are generally directed to layers that are useful in imaging apparatus members and components, for use in electrophotographic, including digital, apparatuses. More particularly, the embodiments pertain to an electrophotographic imaging member having a charge transport layer in which a charge transport molecule (CTM) concentration gradient is formed through a single coating pass using only a single charge transport layer solution, and time-of-flight based methods of measuring the CTM gradient through the thickness of the charge transport layer.
