A drive apparatus that drives a display medium that includes display and rear substrates, a disperse medium, and a particle group, includes a voltage application unit that applies first and second voltages to the display medium, in which, when a color of the particle group is displayed, the voltage application unit applies the first voltage higher than or equal to a threshold voltage necessary for the particle group to be detached from the display substrate or the rear substrate to a pixel where the particle group is moved between the substrates and applies the second voltage having a same polarity as the first voltage and is lower than the threshold voltage to the pixel where the particle group is moved between the substrates and to a pixel adjacent to the pixel where the particle group is moved between the substrates and the particle group of which is not moved.

A display medium is provided. The display medium includes a pair of electrodes disposed so as to have a gap therebetween, an electrolyte disposed between the pair of electrodes, an electroconductive porous layer disposed at least one of the pair of electrodes at the side facing the other electrode, a first electrochromic dye held by the porous layer, a second electrochromic dye dispersed in the electrolyte and forming a color different from the color of the first electrochromic dye. Both the first electrochromic dye and the second electrochromic dye are oxidation dyes which form colors by an electrochemical oxidation reaction and are rendered color-faded by an electrochemical reduction reaction, or reduction dyes which form colors by an electrochemical reduction reaction and are rendered color-faded by an electrochemical reduction reaction. The threshold values of voltages applied to the pair of the electrodes for changing from a color-faded state to a colored state of the first electrochromic dye and the second electrochromic dye satisfy a specific relationship.

A UV-curable coating agent contains a water-absorptive filler having mean particle size of 0.4 μm or less and maximum particle size of 4 μm or less, and viscosity of the coating agent is 30 Pa·s or less. The coating agent is applied on a surface of the base material to form an ink-receiving layer. In order to manufacture the coating agent, after the water-absorptive filler is added to UV-curable monomer, the water-absorptive filler is subjected to wet-grinding.

An image forming method and an image forming apparatus which are capable of jetting ink having high viscosity stably without incremental energy consumption, at a small quantity, and at high speed, and capable of forming high quality and highly precise images without feathering and bleeding on various recording media at high speed are provided. Color ink is held on a flat surface of an ink carrier in the form of a uniform pattern, and the ink carrier is partially heated correspondingly to image information. Then, an air layer is formed on the interface or near the interface between the ink carrier and the color ink. The color ink is jetted by the pressure generated when the air layer is formed to adhere on a recording medium, and thus an image is formed. Particularly, the color ink held on the ink carrier in the form of isolated ink droplets receives an extremely low and uniform resistance force due to the peripheral color ink, therefore, even though color ink having high viscosity is used, ink droplets are jetted stably with small energy and at high speed for recording.
