- Degree of swell (%)=(d-d.sub.0).div.d.sub.0 .times.100
- wherein d.sub.0 is a total thickness of hydrophilic colloid layers and d is a thickness of the hydrophilic colloid layers after having been dipped in distilled water at 25.degree. C. over a period of one minute;
- (b) said developer solution comprises
- (b1) an absorbic acid-like compound represented by formula �A-a! ##STR46## wherein R.sub.3 represents a hydrogen atom, an alkyl, aryl, amino or alkoxy group, each of which may be substituted, a sulfo group, a carboxy group, an amide group, or a sulfonamide group; Y.sub.1 represents a sulfur or oxygen atom; Y.sub.2 represents a sulfur or oxygen atom, or NR.sub.4, in which R.sub.4 represents an alkyl or aryl group, each of which may be substituted;
- (b2) an auxiliary developing agent which is either a 3-pyrazolidone compound or an aminophenol compound;
- (b3) a carbonate salt in an amount of 0.35 mol/l or more; and
- (b4) substantially no dihydroxybenzene compound; and
