Abstract
Abstract A wet developing stationary electrode for wet-developing an electrostatic latent image produced on a record sheet. The electrode is provided at that surface thereof which is opposed to the electrostatic latent image produced surface of the record sheet with a number of strip-shape electrodes acting as developing electrodes and extending along two directions symmetrically inclined with respect to the advancing direction of the record sheet, the rear ends of the strip-shaped electrodes, viewed in the advancing direction of the record sheet, being divergent toward the front ends thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
In a wet-developing stationary electrode for wet-developing an electrostatic latent image produced on a record sheet, the electrode comprising a plate, the improvement comprising a number of strip-shaped electrodes each acting as a developing electrode and opposed to that surface of said record sheet on which is produced said electrostatic latent image, said strip-shaped electrodes extending along two directions symmetrically inclined with respect to the advancing direction of said record sheet and having rear ends, viewed in the advancing direction of said record sheet, which are divergent toward the front ends thereof, said plate having hole means distributed between said strip-shaped electrodes.
Claim 2
Dependent Claim
102 words
In a wet-developing stationary electrode for wet-developing an electrostatic latent image produced on a record sheet, the electrode comprising a plate, the improvement comprising a number of strip-shaped electrodes each acting as a developing electrode and opposed to that surface of said record sheet on which is produced said electrostatic latent image, said strip-shaped electrodes extending along two directions symmetrically inclined with respect to the advancing direction of said record sheet and having rear ends, viewed in the advancing direction of said record sheet, which are divergent toward the front ends thereof, said plate having hole means distributed between said strip-shaped electrodes.
Claim 3
Dependent Claim
32 words
The stationary electrode according to claim 1 wherein said plate of said electrode is electrically conductive and acts as a guide member, said hole means extending along elongate lines between adjacent electrodes.
Claim 4
Dependent Claim
19 words
The wet-developing stationary electrode according to claim 1 wherein said strip-shaped electrodes comprise electrically conductive wires on said plate.
Claim 5
Dependent Claim
35 words
The wet-developing stationary electrode according to claim 1 wherein said plate is insulating and said strip-shaped electrodes comprise a number of ridges on said plate, said ridges being coated with electrically conductive plated layers, respectively.
Claim 6
Dependent Claim
27 words
The wet-developing stationary electrode according to claim 3 wherein said hole means is constituted by a number or small holes disposed in said plate between the wires.
Claim 7
Dependent Claim
28 words
The wet-developing stationary electrode according to claim 4 wherein said hole means is constituted by a number of small holes disposed in said insulating plate between said ridges.
