ABSTRACT:
The present invention provides a developing method for electrophotography which is developed to perform the development by electrically insulating the developing electrode from the support of the photosensitive material, together with apparatuses suitable for practicing said method. This developing method is applicable to both the wet inversion development and the magnetic brush inversion development, and produces a negative-positive image having a satisfactory reproducibility particularly with respect to the solid image area thereof.
