Claims
- 1. In a copy paper separator disposed opposite to a photosensitive body surface and having a separation charger with a charger wire therein and a transfer charger adjacent to said separation charger and having a boundary wall with said separation charger, the improvement comprising
- an elongated charge controlling sheet made of a narrow belt-like insulator designed and disposed between said charger wire and said photosensitive body surface such that, when said separation charger is discharged, the total charge received by said photosensitive body surface from said charger wire is significantly less but the maximum current on said photosensitive body surface received from said charger wire is not less than if said charge controlling sheet were absent, and
- an insulative separator plate attached to said boundary wall protrudingly towards said photosensitive body surface so as to form an adjustably determined gap between said insulative separator plate and said photosensitive body surface, whereby whitening of copy paper processed on said photosensitive body surface is reduced.
- 2. The copy paper separator of claim 1 wherein said charge controlling sheet is disposed parallel to said photosensitive body surface.
- 3. The copy paper separator of claim 1 wherein said gap is so adjusted as to help copy paper to separate efficiently from said photosensitive body surface without causing whitening of said copy paper.
