Patent ID: 7379694

Claim:
A belt transfer apparatus, comprising: a belt-shaped transfer member having contact with a surface of a photoreceptor of an image forming apparatus to sandwich a recording sheet therebetween; a primary transfer current path on which a current from a high-voltage power source passes through the transfer member and then the photoreceptor; and a secondary transfer current path on which a current from the high-voltage power source passes through the transfer member in a different direction than the primary transfer current path, wherein a voltage drop V 1 resulting at the transfer member when a current I 1 passes on the primary transfer current path and a voltage drop V 2 resulting at the transfer member when a current I 2 which is smaller in absolute value than the current I 1 passes on the secondary transfer current path, satisfy the expression: |V 1 /I 1 |/|V 2 /I 2 |<1.
