摘要： An image forming apparatus of the present invention includes an image transferring device for transferring a toner image from an image carrier to a recording medium and a moving device for selectively moving the image transferring device toward or away from the image carrier. The moving device moves the image transferring device toward the image carrier on the elapse of at least a period of time necessary for the image carrier to rotate from a rotation start position to a reversely rotated position. Assume that a distance between a position where the image transferring device approaches the image carrier and a position where the toner image starts being formed on the image carrier is a, that the image carrier is reversely rotated by a distance of b, that the linear velocity of the image carrier is V, and that a period of time between the start of rotation of the image carrier and image formation is c, then a period of time t necessary for the image transferring device approaches the image carrier after the start of rotation of the image carrier is satisfies a relation of (a+b)/V

摘要： An image transferring and sheet separating device of the present invention includes a belt facing an image carrier. The belt conveys a sheet via a nip between it and the image carrier to thereby transfer a toner image formed on the image carrier to the sheet by being applied with a bias and then separates the sheet from the sheet. The belt contains a filler having a grain size of 0.5% to 5% of the thickness of said belt. The belt is driven with circumferential length 1% to 7% greater than circumferential length in an unloaded condition.
