The phenomena of paper sheet adsorption to the photoreceptor are wellknown during the corona charge transfer process, in that corona charging is performed directly to the paper sheet. However, even in using the roller transfer and belt transfer methods in that the charging was made not directly to the sheet but to an insulator of the roller or belt, similar phenomena were often experienced due to the charge injection from the insulator to the paper sheet. For such a charge injection process from a charged insulator to a paper sheet, the process due to Paschen's discharge was considered and argued. As a result, theoretical consideration indicates that Paschen's discharge may occur through the air gap due to the proejction of the sheet edge, and actually we have succeeded in observing the Paschen's discharge in the air gap.
