Imaging apparatus including an imaging surface, apparatus for forming a latent image comprising image areas at a first electrical potential and background areas at a second electrical potential on the imaging surface, and developing apparatus for developing the la- tent image with a liquid toner including charged toner particles and a carrier liquid. The developing apparatus includes a developer roller electrified to a third electrical potential intermediate the first and sec- and electrical potentials and having a portion thereof closely spaced from the imaging surface to form a development region therebe- tween, whereat the latent image is developed with liquid toner and li- quid toner supply apparatus for supplying the liquid toner to the de- velopment region thereby developing the latent image, whereby toner particles are also attracted to the developer roller. The developing ap- paratus also includes a resilient metal blade at least partially coated with an insulating coating, urged against the developer roller for removing toner particles from the developer roller. Alternatively or additionally the surface of the developer roller is formed with an in- sulating surface layer.
