Abstract
Abstract A multicolor printing device comprises latent image formation means (3), which form an electrostatic latent image corresponding to a plurality of colors on a latent image formation medium (1), and developing means (4, 6, 8), which develop the colors of the electrostatic latent image. To avoid unwanted color mixing, respective different developable areas are predefined for different working colours of the image to be printed, and separate developer outlets are provided for developing the said different areas respectively.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
70 words
A multicolor printing device comprising a latent image formation means, which forms an electrostatic latent image corresponding to a plurality of colors on a latent image formation medium, and a plurality of developing means which develop the colors of said electrostatic latent image characterized in that a means which defines a developable region with regard to the colors of said latent image is provided with the plurality of developing means.
Claim 2
Dependent Claim
70 words
A multicolor printing device comprising a latent image formation means, which forms an electrostatic latent image corresponding to a plurality of colors on a latent image formation medium, and a plurality of developing means which develop the colors of said electrostatic latent image characterized in that a means which defines a developable region with regard to the colors of said latent image is provided with the plurality of developing means.
Claim 3
Dependent Claim
33 words
A multicolor printing device according to claim 1, characterized in that said means which defines the colors of said developable region is provided between said latent image formation medium and said developing means.
Claim 4
Dependent Claim
37 words
A multicolor printing device according to claim 2, characterized in that said means which defines the colors of said developable region is formed by a plate having openings at development positions of said plurality of developing means.
Claim 5
Dependent Claim
74 words
A multicolor printing device including latent image formation means, for forming on an image formation medium a latent image having different regions associated respectively with different colours, and developing means for developing the said regions differently from one another so that the said different colours are manifested respectively at the regions associated therewith, characterised in that the manifestation of different working colours is restricted respectively to predefined different adjacent areas of the image medium.
Claim 6
Dependent Claim
74 words
A multicolor printing device including latent image formation means, for forming on an image formation medium a latent image having different regions associated respectively with different colours, and developing means for developing the said regions differently from one another so that the said different colours are manifested respectively at the regions associated therewith, characterised in that the manifestation of different working colours is restricted respectively to predefined different adjacent areas of the image medium.
Claim 7
Dependent Claim
22 words
A device as claimed in claim 4, wherein the said predefined different adjacent areas are narrow elongate areas extending alongside one another.
Claim 8
Dependent Claim
40 words
A device as claimed in claim 4 or 5, wherein the developing means have different outlet openings, for delivering respective developers for the different working colours, which openings are arranged in register respectively with the said predefined different adjacent areas.
