a second movement restricting unit that restricts movement of the second tubular member in an axial direction of the cap member.
4. The powder container according to claim 1 , wherein
the container body includes
an opening that discharges contained powder to an outside, and
a cap member that is attached to the container body to seal the opening and equipped with a second opening that is communicated with the opening, and
the cap member attached to the container body covers the information storage unit.
5. The powder container according to claim 4 , wherein
the movement restricting unit is a flange portion that is to be engaged with an engaging portion formed on the cap member, and
the information storage unit and the opening are located so as to sandwich the flange portion.
6. The powder container according to claim 5 , wherein the container body is supported by the cap member so as to be rotatable with respect to the cap member.
7. The powder container according to claim 1 , further comprising a rotation restricting unit that restricts rotational movement of the tubular member in a circumferential direction with respect to the container body.
8. The powder container according to claim 1 , wherein the tubular member is formed such that a rectangular member is wound around an outer peripheral surface of the container body and then both end portions of the rectangular member in a longitudinal direction are stuck to each other.
9. The powder container according to claim 1 , further comprising an information transmitting-receiving unit that is electrically connected to the information storage unit and configured to transmit and receive the information to and from an external communicating unit, wherein
the tubular member is an electronic substrate, and
the information transmitting-receiving unit is arranged on the entire circumference of the electronic substrate.
