PURPOSE:To obtain good images even if the environment at the time of forming copied images fluctuates by incorporating a specific resin, thermosetting resin contg. a crosslinkable functional group and crosslinking agent into a binder resin. CONSTITUTION:The binder resin contains the resin A, the thermosetting resin contg. the crosslinkable functional group and the crosslinking agent. The resin A is the copolymer which has 1X10<3> to 2X10<4> weight average mol. wt. and consists of a monofunctional macromonomer M which is bonded with the polymerizable double bonds expressed by the formula I only at one terminal of the main chain of the polymer having at least one kind of polymer components expressed by the formulas IIa and IIb and has <=2X10<4> weight average mol. wt., and a monomer expressed by the formula III. The above- mentioned copolymer contains the substituent selected from a -PO3H2 group, etc., only at the one terminal of the copolymer main chain. In the formulas, V and X0 denote -COO, etc.; a1, a2, b1, b2, c1, c2 denote a hydrogen atom, etc.; Q0, Q1 denote 1 to 18C aliphat. group, etc.; Q denotes -CN, etc. The stable characteristics are maintained in this way even if the environment fluctuates. |
