PURPOSE:To obtain a recording member with superior fixing sensitivity, high contrast and high resolving power by forming a specified fixing layer, an intermediate layer and a color developing layer on a support in order. CONSTITUTION:On a support a 5-20mum thick fixing layer is formed consisting of a Co (III) amine complex and/or a Co(III) amine complex (a), a photoreducing agent (b), a hydrogen donor (c) and a dioxime chelating agent represented by formula I (where each of R1 and R2 is alkyl, aryl or aralkyl and n is 0-3) or a diantipyrinylmethane chelating agent (d) represented by formula II (where each of R3-5 and R'3-5 is H, alkyl or aryl and each of R6 and R7 is H, alkyl, optionally substituted aryl or aralkyl), and on the fixing layer a 1-10mum thick intermediate layer consisting of TiO2 (e) having 0,05-20mum particle size and a water soluble resin or an emulsion resin (f) as a binder and a 1-20mum thick color developing layer consisting of a photo-oxidizing agent (g), a coupler (h) which develops color by oxidation and an acid (i) accelerating the color development are formed in order. |
