Claim:
A liquid droplet deposition method of consecutively depositing a plurality of droplets of liquid onto a recording medium, the liquid containing solvent and particles dispersed in the solvent, the particles having a substantially uniform size, the method comprising the steps of: determining target positions at which the plurality of droplets are to be deposited on the recording medium; depositing an X-th droplet of the droplets at an X-th target position of the determined target positions on the recording medium, X being a natural number; and depositing an (X+1)-th droplet of the droplets at an (X+1)-th target position of the determined target positions on the recording medium subsequently to the X-th droplet, after the particles contained in the X-th droplet are aggregated to form an X-th particle aggregate on the recording medium due to liquid bridging force, wherein in the determining step, the target positions are determined so as to satisfy following conditions: L ( C X , C X+1 )≦ r X +r _max X+1 , and L ( P X , C X+1 )≧ r _max X+1 , where C X is the X-th target position, C X+1 is the (X+1)-th target position, L(C X , C X+1 ) is a distance between C X and C X+1 , r X is a radius of the solvent of the X-th droplet on the recording medium at a time of depositing the (X+1)-th droplet on the recording medium, r_max X+1 is a radius of the solvent of the (X+1)-th droplet at a time of maximumly spreading on the recording medium, P X is a position of an edge of the X-th particle aggregate on a line connecting C X and C X+1 , and L(P X , C X+1 ) is a distance between P X and C X+1 .
