Abstract
A sheet conveying device and an image forming apparatus include a conveying member that adsorbs a sheet by an electric charge and conveys the sheet, a first electric charger to charge the conveying member by applying voltage, and a second electric charger to charge the conveying member by applying voltage. The second electric charger is arranged downstream from the first electric charger in a conveying direction, and applies the electric charge with the same polarity as the first electric charger to the conveying member.
Claims9
A sheet conveying device, comprising:
- a conveying member that adsorbs a sheet by an electric charge electrified on a surface, and conveys the sheet in a prescribed conveying direction;
- a first electric charger to charge the conveying member by applying voltage;
- and
- a second electric charger to charge the conveying member by applying voltage,
- wherein the second electric charger is arranged downstream from the first electric charger in the conveying direction, and the second electric charger applies the electric charge with the same polarity as the electric charge applied by the first electric charger at a position of the conveying member that faces the second electric charger, such that the conveying member is charged with the same polarity.
An image forming apparatus, comprising:
- a printing device that forms an image on a printing medium;
- a conveying member that adsorbs the printing medium by an electric charge electrified on a surface, and conveys the printing medium with the image in a prescribed conveying direction;
- a first electric charger to charge the conveying member by applying voltage;
- a second electric charger to charge the conveying member by applying voltage;
- and
- a sheet feeding device that feeds the printing medium to the electrified conveying member,
- wherein the second electric charger is arranged downstream from the first electric charger in the conveying direction, and the second electric charger applies the electric charge with the same polarity as the electric charge applied by the first electric charger at a position of the conveying member that faces the second electric charger, such that the conveying member is charged with the same polarity.
A sheet conveying device, comprising:
- a conveying member that adsorbs a sheet by an electric charge electrified on a surface, and conveys the sheet in a prescribed conveying direction;
- a first electric charger to charge the conveying member by applying voltage;
- and
- a second electric charger to charge the conveying member by applying voltage,
- wherein the second electric charger is arranged downstream from the first electric charger in the conveying direction, and applies the electric charge with the same polarity as the first electric charger, to the conveying member, and
- wherein a variable resistor is arranged on an electric supply wiring between the first electric charger and a power supply.
