PROBLEM TO BE SOLVED: To improve display switching responsiveness by reducing collisions between electrophoretic particles and turbulence when switching a display of an electrophoresis device. SOLUTION: In the driving method of the electrophoresis device, an electrophoresis layer 20 containing white and black electrophoretic particles different by electric polarities is provided between a pixel electrode 13a and a transparent electrode layer 32, and electrophoretic particles are moved to the side of one electrode by voltage application between electrodes to form an image. The driving method includes; a first step of applying different voltages to a sub-pixel electrode 13a-1 and a sub-pixel electrode 13a-2 before display switching to maldistribute electrophoretic particles distributed on the side of the pixel electrode 13a, on the sub-pixel electrode 13a-1 or the sub-pixel electrode 13a-2; and a second step of moving electrophoretic particles by reversing polarities of the pixel electrode 13a and the transparent electrode layer 32, to switch the display.
