The present invention provides an anti-solvent laminate body baying an excellent anti-solvent characteristic when used in a solvent atmosphere or a manufacturing method thereof. In the anti-solvent laminate body used in a solvent atmosphere comprising a substrate portion or a manufacturing method thereof an which an electrostatic latent image developing toner is printed and a printing portion formed of the electrostatic latent image developing toner, wherein the electro latent image developing toner contains a binder resin which has a solubility parameter (SP) which is different from a solubility parameter (SP) of a solvent which forms a solvent atmosphere by not lees than about 5(MJ/m)in an absolute value.

Antisolvent-laminate body

A toner, such as an electrostatic latent image developing toner and a MICR toner, has an even charge distribution, and exhibits balanced charging characteristics without decreases in frictional electrification or increases in charge, as well as superior fluidity, environmental independence, and durability. This is achieved by treating toner particles, which include binder resin and magnetic particles, with an external additive particle that is one of: a combination of rutile-type titanium oxide and anatase-type titanium oxide; and rutile-type titanium oxide that falls in a range of 5 to 10% by volume when a total volume of the toner is regarded as being 100%.
