A surface treatment apparatus which can efficiently form fine depressions and protrusions on a sheet selected from an inkjet sheet, a thermosensitive recording sheet, a heat developing sheet, an electrophotographic sheet, and a silver halide photographic sheet, and an image-forming apparatus incorporating this surface treatment apparatus, are provided. Upon receipt of the search query, a search system accesses a persistent descriptor corresponding to a detected version of the product. At the same time as the above two steps are being performed, the treatment method includes providing, between the electrodes and the patient’s skin, at least two solution-absorbing pads electrically insulated from each other and each one of the two solution-absorbing pads being in electrical contact with one or more of the electrodes on the head of the probe. Side walls are included to limit the distance a card may be inserted into the card attachment.
