To provide an image carrier such as a copy paper capable of being repeatedly used for image formation which can easily be separated and distinguished from a general image carrier even through the image carrier is piled up coexistentily with the general image carrier with can not be repeatedly used or which is not adequate for being repeatedly used.

This image carrier 1 capable of being repeatedly used for the image formation is provided with discriminating display for distinguishing the image preserving body from the one which can not be processed to be recycled so that it may be reused in the image formation or which is not adequate for the recycling processing on a side end surface. The discriminating display can be formed of a coloring part 1a colored to have density whose light absorbing degree on the maximum absorbing wavelength of spectral reflection is ≥0.3 by using a coloring material in a visible area, for example. The body 1 capable of being repeatedly used for the image formation can be constituted so as to have an external shape size different from the of the general image preserving body, or one part of the side end edge part can be notched.
