Patent ID: 8246161

Claim:
A conveying apparatus comprising: a conveyance carrier configured to attract and convey a recording medium; a voltage applying unit configured to apply a voltage to the conveyance carrier to generate electrostatic attraction force on a surface of the conveyance carrier; a static charge eliminating unit configured to eliminate charges on a surface of the recording medium which are electrostatically attracted to the conveyance carrier and the surface of the conveyance carrier outside an area where the recording medium is attracted; a reverse voltage applying unit configured to apply a voltage which has a polarity reverse to that of the voltage applied by the voltage applying unit to the conveyance carrier at a downstream side of the static charge eliminating unit to weaken the electrostatic attraction force of the conveyance carrier; and a humidity detecting unit configured to detect humidity in the vicinity of the surface of the conveyance carrier, wherein the reverse voltage applying unit changes the reverse voltage to apply the voltage based on the value detected by the humidity detecting unit.
