A method of forming a color image comprising providing a first peelable transfer layer 12 on an electrophotographic light-sensitive element 11 whose surface has releasability, forming one or more color toner images 3 on the first transfer layer by a conventional electrophotographic process, further forming a second transfer layer 13 on the toner images 3, and transferring the toner images 3 together with the first transfer layer 12 and the second transfer layer 13 to a receiving material 16 is disclosed. The method is excellent in transferability of toner image and provides simply and stably color images of high accuracy and high quality without color shear. The transfer layer has good releasability from an electrophotographic light-sensitive element and good adhesion to a receiving material. A color duplicate formed has good retouching property, sealing property and storage stability.

A piezoelectric sensor device includes a piezoelectric element, a polarization processing unit and a controller. The piezoelectric element has a pair of electrodes sandwiching a piezoelectric body. The polarization processing unit is configured to execute polarization processing in which polarization voltage is applied to the polarization element. The controller is configured to control an execution timing of the polarization processing by the polarization processing unit, and includes a characteristics value acquisition unit configured to acquire a characteristics value relating to a polarization volume of the piezoelectric body, a determination unit configured to determine whether a polarization property is in a stable state or in an unstable state based on the characteristics value, and a polarization controller configured to control the polarization processing unit to apply the polarization voltage to the piezoelectric body when the determination unit determines that the polarization property of the piezoelectric body is in the unstable state.
