Abstract: Novel packing cases for image forming sheets are invented. An image forming machine, such as a color hard copying machine uses image forming sheets which are coated on their surfaces with image forming material. Since the image forming material easily comes off from the surface of an image forming sheet, the surface must be protected from physical contacts, particularly during transportation, handling, storing, etc. The novel packing cases are not only provided with protective sheets to protect image forming sheets accommodated in the packing case, but also with other inventive features to avoid any possible physical contacts with the surface of the image recording sheet.
