A writing implement with a thermochromic coloring color-memory composition which comprises a homogeneous solubilized mixture of an electron donative coloring organic compound, an electron accepting compound and a reaction medium which controls color reactions of the components and, wherein a complete decoloring temperature of the thermochromic coloring color-memory composition is 50\xb0 C. The housing includes a fixing portion, an opening and a receiving chamber communicating with the opening. Compensation parameters are set based on the calculated block distortion ratios. A second conductive layer is formed on the crystallized first conductive layer.
