1. A portable radiation detector comprising:
a housing;
a wireless communication section accommodated in the housing, to carry out wireless communication of image data of a detected radiation image;
a cable having one end portion connected to the housing;
a connector provided at another end portion of the cable, and configured to be connected to an external device; and
a connector holding mechanism provided at the housing, and holding the connector removably at the housing, wherein the connector is configured to be connected to the external device in a state in which the connector is held at the housing and the housing is set in the external device.
2. The portable radiation detector of claim 1, wherein:
the cable is a cable for electric power supply; and
a first power supply device is the external device.
3. The portable radiation detector of claim 2, wherein the connector can be connected to a second power supply device that is the external device, in a state in which the connector is removed from the housing.
4. The portable radiation detector of claim 1, wherein:
the cable is a cable for electric power supply; and
the connector can be connected to a second power supply device that is the external device, in a state in which the connector is removed from the housing.
5. The portable radiation detector of claim 3, wherein the cable also serves as a cable for carrying out wired communication of the image data, and the portable radiation detector further comprises:
a wired communication section accommodated in the housing, to carry out, with the cable and with at least one of the first power supply device or the second power supply device, wired communication of image data of a detected radiation image; and
a switching section, accommodated in the housing, for switching between the wired communication section and the wireless communication section.
6. The portable radiation detector of claim 1, wherein the cable serves as a cable for carrying out wired communication of the image data, and the portable radiation detector further comprises:
a wired communication section accommodated in the housing, to carry out, with the cable and with the external device, wired communication of image data of a detected radiation image; and
a switching section, accommodated in the housing, for switching between the wired communication section and the wireless communication section.
7. The portable radiation detector of claim 1, further comprising a cable holding mechanism that holds the cable along an outer periphery of the housing.
8. The portable radiation detector of claim 1, further comprising a take-up mechanism that takes-up the cable at an interior of the housing.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A replenishment toner for use in an image forming apparatus that detects a toner concentration in a two-component developer by use of a magnetic permeability detecting means,
wherein a percentage by volume of toner particles with particle diameters of 5.04 m or smaller contained in the replenishment toner is in a range from 1.5 to 3.5 times a percentage by volume of such toner particles contained in an initial toner loaded initially in the image forming apparatus.
2. A replenishment toner as claimed in claim 1,
wherein a median particle diameter on a volume basis of the replenishment toner is in a range from 8.0 to 12.0 m.
3. A replenishment toner as claimed in claim 1,
wherein a median particle diameter of the replenishment toner is equal to a median particle diameter of the initial toner.
