Abstract: A packing member, a toner container, and a packing method. The packing member contains the toner container, and the packing member includes a box containing the toner container with a gap between one side of the box and a container body and between the one side of the box and a large-dimension portion of the toner container, a first pressing portion that presses the container body, and a second pressing portion that presses the large-dimension portion. In the packing member, the large-dimension portion of the toner container is disposed at one end of the container body, and the large-dimension portion has a wider dimension than the container body in a direction orthogonal to a longitudinal direction of the toner container. In the packing member, the container body contacts, with first contact force, a first bearer inside the box to maintain the gap.

Abstract: An injection control apparatus includes an injection member; a drive section for injection; an injection-speed detection processing section which detects injection speed; an injection-pressure detection processing section which detects injection pressure; and a drive control processing section which drives the drive section for injection on the basis of the injection speed and the injection pressure to thereby perform pressure control before start of charging of a molding material into a cavity, and speed control after the start of charging of the molding material into the cavity. Since the drive section is driven on the basis of the injection speed and the injection pressure such that pressure control is performed before start of charging of a molding material into a cavity, and speed control is performed thereafter, the pressure of the cavity after the molding material has entered the cavity becomes stable and uniform.
