Abstract
Abstract A laminate film suitable for providing a transparency for an OHP (overhead projector) is formed by disposing an absorbing layer on a substrate. The absorbing layer functions to allow addition of a wax component to a toner so as to improve the color mixing characteristic and anti-offset characteristic of the toner without causing a wax exudation trace which is liable to occur in a fixed toner image if the absorbing layer is not provided.
