PROBLEM TO BE SOLVED: To provide a method for automatically measuring resistance values in conductive rubber rollers capable of obtaining stable measured values and performing measurements close to an operating state by continuously rotating the rubber rollers 1 and automating the measurements. SOLUTION: In the method for automatically measuring resistance values in conductive rubber rollers, the following processes, that is, a transferring process to transfer the rubber rollers 1 one by one, a setting process to receive the rubber rollers 1 one by one and to make the rubber rollers 1 closely adhere to a measuring roller 2 with conductivity, a resistance value measuring process to automatically measure contact parts at a plurality of locations in the circumferential direction of the rubber rollers 1 as rotating the measuring roller 2, a determining process to automatically determine whether the measured value lies within the range of specifications or not, and a classifying process to classify the rubber rollers 1 into conforming items, items superior to the specifications, and items inferior to the specifications according to the determination of the determining process and to automatically transfer them, are sequentially performed.
