Abstract: Examples disclosed herein relate to magnetic carrier bead separation in dual-component printing. The present disclosure relates generally to a device, method, and system for magnetic carrier bead separation. In an example, a printing device includes a developer sump to hold a plurality of carrier beads. The example device also includes a roller to move a subset of the plurality of carrier beads from an attachment point on the roller to a release point through a rotation of the roller, wherein the subset of the plurality of carrier beads return towards the developer sump after they are released at the release point. The device includes a magnetic separator located between the release point and the attachment point that guides a magnetized carrier bead of the plurality of carrier beads away from the developer sump and the roller.
