Sheet guiding apparatus with an electric field or charge inverting portion

A sheet guiding apparatus, comprising:

• a supporting member formed of a dielectric material having a supporting surface which supports a sheet;
• a first electrode provided in the supporting member so as to be distant from the supporting surface;
• an electric field generating portion configured to generate an electric field between the supporting surface and the first electrode by applying a voltage to the first electrode;
• a guide member which is distant from the supporting surface by a predetermined distance in a direction perpendicular to the supporting surface and which defines a path extending to the predetermined position;
• a moving portion configured to move the sheet supported by the supporting surface by moving at least one of the supporting member and the guide member relatively to each other in a direction parallel to the supporting surface;
• and
• an electric field inverting portion configured to invert a direction of the electric field generated by the electric field generating portion, before a leading end portion of the sheet has moved in a direction in which the sheet is moved to reach the guide member.
