Developing cartridge including holder movably supporting electrical contact surface

Abstract

A developing cartridge includes: a housing extending in a first direction; a developing roller; a memory held at the housing; a holder holding an electrical contact surface; and a relay component electrically connecting the memory to the electrical contact surface. The developing roller is rotatable about an axis extending in the first direction. The developing roller is positioned at one end portion of the housing in a second direction. The holder is movable relative to the housing in at least one of the second direction and a third direction crossing the first direction and the second direction. The third direction also crosses the electrical contact surface.
