摘要： A transfer device includes a photosensitive drum on the outer surface of which an image to be transferred is formed; a transfer drum arranged in parallel to the photosensitive drum and substantially in contact with the outer surface of the photosensitive drum, the transfer drum capable of adsorbing a sheet on its outer surface; and a sheet guide for guiding the sheet supplied toward the transfer drum to a transfer position between the photosensitive drum and the transfer drum. At an end of the sheet guide on the side of the transfer position, a hill-shaped guide is provided which flexes at a flexing point in a plane orthogonal to the rotary axis of each of both drums so as to be convex toward the photosensitive drum. The side of the hill-shaped guide from the flexing point toward, and closest to, the transfer position is inclined toward the photosensitive drum with respect to a tangent of the photosensitive drum passing the transfer position.
