Abstract
An image transfer device includes a member for carrying a transfer material thereon and an image bearing member having an image thereon, the transfer material carrying member being subjected to a transfer corona therethrough to transfer the image from the image bearing member onto the transfer material. When the transfer material is separated from the transfer material carrying member by a separation pawl, that portion of the transfer material carrying member from a position in which the transfer material is in close contact with the carrying member to another position in which the transfer material is separated from the carrying member by the separation pawl is charged by a pair of corona chargers with the transfer material carrying member being located therebetween, so that the transfer material can more readily be separated from the carrying member.
