PROBLEM TO BE SOLVED: To provide a method for producing a solid paper quality-improving agent, by which the solid paper quality-improving agent which has a bulkiness-imparting effect, is excellent in a sizing property, and can improve productivity on the production of paper due to a low water-holding property in a paper-making process can be produced. SOLUTION: This method for producing the solid paper quality-improving agent has the step of reacting an amide amine composition (a) having an imidazoline content of 0 to 10% and obtained by reacting a 10 to 24C fatty acid and/or its ester (b) with polyethylenepolyamine (c), with epichlorohydrin at 50 to 140°C.
