Abstract: A liquid developer reservoir for use in a copying machine comprises at least two sections one of which is adapted to receive a photosensitive paper carrying an electrostatic latent image formed thereon and to be subjected to the developing operation. Developing liquid is supplied to one of the sections and led out from the other section, both sections being connected to each other to permit the developing liquid to flow from the former to the latter. A vertical partition separates one section of the reservoir from the other and has an aperture at the bottom thereof for providing the desired liquid flow between the sections.

Abstract: A multicolor electrophotography apparatus and method wherein a photoconductive copy sheet surface containing uniform electric charge is exposed to an original through light filter which enables one color to be recorded, is developed with colored toner to produce a copy of that color, and the sequence is repeated for each of the other colors, utilizing superimposing toner images on the same copy sheet. In a preferred embodiment a sheet carriage is adapted to hold the copy sheet at its upper edge portion and carry it only in a certain direction for example in a vertical direction whereas a developer bed on which a plurality of developer reservoirs, each containing different colored developer toners are mounted, is adapted to travel in the other direction for example in the horizontal direction.
