An ink container has a cylinder provided with an ink discharge port at its leading end and a piston fitted in the cylinder to be slidable along the inner surface of the side wall of the cylinder. Ink is filled into the space defined by the cylinder and the piston. Resistance generated by friction between the cylinder and the piston when the piston is slid toward the ink discharge port with the ink container held empty is not lower than 1.0N.

An image processing apparatus furnished with an overhead projector has an image projecting function and an image-forming function. The image processing apparatus is designed to detect the movement of an original support table or a reflection-type focusing plate during projecting of an original. The result is that the original support table is free from being heated by the focusing plate and also that the focusing plate is free from any deviation of its axis of light, thus preventing the reflected light from striking on the eyes of the operator.
