An ink roller comprises a moulded plastics tube 351, the interior of which serves to hold a supply of ink. Feed holes 352 in the wall of the tube lead to external grooves 353 to cylindrical sleeves 358, 359 of porous ink-receptive material. The two ends of the tube 351 are closed by snap fit end plugs 365 formed with central stub shafts 367. To prevent warpage and other distortion of the tube 351, it is formed with a central external flange 357 which may also form an external guide surface. <IMAGE>
