Method for manufacturing removable information sheet

A method for manufacturing a removable information sheet, the method comprising:

• forming a toner image on a recording medium with use of a toner;
• applying an energy ray-curable pressure-sensitive composition precursor onto the recording medium with the toner image formed to form an energy ray-curable pressure-sensitive composition precursor layer;
• irradiating, with an energy ray, the recording medium with the energy ray-curable pressure-sensitive composition precursor layer formed to cure the energy ray-curable pressure-sensitive composition precursor layer and form an energy ray-curable pressure-sensitive composition;
• and
• attaching faces with the energy ray-curable pressure-sensitive composition formed to each other and pressure-bonding the faces,
• wherein a size of a region of a toner image flat part, determined by a measurement method, is 200 μm or less in the toner image formed by the forming, and
• wherein the measurement method includes:
• defining, in a solid part of the toner image, a site at a depth of 2 μm or more from a surface of the solid part as a recess;
• defining a site other than the recess as the toner image flat part;
• acquiring a micrograph of the solid part of the toner image;
• binarizing the micrograph;
• drawing circles out of contact with the recess in the toner image flat part;
• and
• defining a diameter of a largest circle among the circles drawn as the size of the region of the toner image flat part.
