Disclosed is an image receiving sheet for forming a toner image by removably adhering toner thereto. The sheet has an irregular surface including a plurality of concavities in the form of continuous grooves for receiving the toner and ridges extending along the concavities, and a toner image can be formed by removably adhering the toner to the concavities. The ridges of the irregular surface are capable of protecting the toner adhering to the concavities. The continuously grooved concavities have a depth (height of ridges) of 20 μm to 150 μm; and a condition of E·A≧2 [GPa·μm] can be established wherein E[GPa] means Young's modulus and A [μm] means a width of ridges, the Young's modulus being a value when a material for forming the concavities and ridges is elongated by 1%. The ridges may be reinforced by reinforcing portions for retaining postures of the ridges.
