Polarization, or "induced dipoles".
The positively charged ruler will pull on the electrons in the paper, and push against the nuclei. The electrons will therefore try to move a tiny bit closer to the ruler. The paper will now have a negatively charged side close to the ruler, and a positively charged side further away. And since the negative side is closer, it is attracted more strongly than the positively charged side is pushed away. This results in a net attractive force.
