Abstract
A charge-eliminating apparatus includes a charge-eliminating member for eliminating charge of a sheet while nipping and conveying the sheet, a voltage applying unit for applying a voltage to the charge-eliminating member, and a detecting unit for detecting a voltage applied to the charge-eliminating member or a current flowing through the charge-eliminating member. A controller measures an electrification charge amount of the sheet based on a detecting result of the detecting unit while the sheet passes through the charge-eliminating member.
Claims18
A charge-eliminating apparatus comprising:
- a charge-eliminating member configured to eliminate charge of a sheet while nipping and conveying the sheet;
- a voltage applying unit configured to apply a voltage to the charge-eliminating member;
- a detecting unit configured to detect a voltage applied to the charge-eliminating member or a current flowing through the charge-eliminating member;
- and
- a controller configured to measure an electrification charge amount of the sheet based on a detecting result of the detecting unit while the sheet passes through the charge-eliminating member.
A charge-eliminating apparatus comprising:
- a charge-eliminating member configured to eliminate charge of a sheet while nipping and conveying the sheet;
- a voltage applying unit configured to apply a voltage to the charge-eliminating member;
- a detecting unit configured to detect a voltage applied to the charge-eliminating member or a current flowing through the charge-eliminating member;
- and
- a controller configured to determine a value of the voltage to be applied to the charge-eliminating member by the voltage applying unit in order to eliminate the charge of the sheet based on a detecting result of the detecting unit while the sheet passes through the charge-eliminating member.
A charge adjusting apparatus comprising:
- a charge supplying member configured to supply charge to a sheet while nipping and conveying the sheet;
- a voltage applying unit configured to apply a voltage to the charge supplying member;
- a detecting unit configured to detect a voltage applied to the charge supplying member or a current flowing through the charge supplying member;
- and
- a controller configured to measure an electrification charge amount of the sheet based on a detecting result of the detecting unit while the sheet passes through the charge supplying member.
