Abstract
Disclosed are printing methods, apparatus and systems for developing a latent image recorded on a surface, for example, a photoreceptor with developer material. According to an exemplary embodiment, the development method applies a development field voltage between a development station donor member and a development station transport member as a function of a humidity measurement associated with the developer material, the humidity measurement providing a surrogate tribo measurement of the developer material.
