Tonerkartusche

摘要

A toner cartridge (20) including an engaging protrusion (26) and an engaging concavity (27) on a capped unit (25) formed at one end surface of a container (21), and on a seal cap capped (22) rotatably on the capped unit, a rotating range limiting opening (31) into which the engaging protrusion (26) fits and a stopping claw (32) disallowing the seal cap to rotate by fitting into the engaging concavity (27) to keep a toner replenishing opening closed. The user can not rotate the seal cap (22) unless he presses down the stopping claw (32), and thus erroneous toner leakage or scattering can be prevented.
