高湿と低湿の環境下での特性試験は重要である。Conventionally, photosensitive drums for electrophotography have been widely used in copiers, printers, and the like. However, the photosensitive drum is made of an inorganic photoreceptor such as selenium or cadmium sulfide, which is non-polluting and mass-produced. The photoconductor (OPC) is developing rapidly. Amorphous silicon (a-Si) using vacuum technology has recently been used. These photoconductors depend on the use environment, and their characteristics change with changes in temperature and humidity. In particular, organic photoconductors (OP
C) is said to have a large change in temperature and temperature, and it is important to perform characteristic tests under high and low temperature environments and high and low humidity environments.

下に保管している。As shown in FIG. 1, in this embodiment, in order to facilitate the temperature / humidity test of the photosensitive drum, various characteristic testers, for example, a charge characteristic tester, an exposure characteristic tester, a defect characteristic tester,
The printing quality evaluation test machine is housed inside the measurement box 1,
In addition, the measurement box 1 and an air control unit 8 for controlling the temperature and humidity are connected by a duct 9, and the air having the controlled temperature and humidity is sent into the box 1. Also,
The box 1 has a drum storage shelf 3 that can store a drum to be measured, and the drum to be measured is stored in the same environment.

る。For example, if you want to perform low-temperature evaluation, if you place the device under test from the outside, you cannot measure it until you wait for the same temperature. Drum condensation forms, making measurement impossible. Therefore, if the drum to be measured is placed in a storage container in the box 1, that is, the drum storage shelf 3 before the measurement, the measurement can be continuously performed in any environment.

本の連続測定が実現される。To explain this in more detail, inside the measuring box 1, there are measuring units 2 such as a charging characteristic tester, an exposure characteristic tester, a defect characteristic tester, and a print quality evaluation tester. On the other hand, the air of temperature and humidity is controlled to an arbitrary temperature and humidity by the air control unit 8, is sent through the duct 5 from the air inlet 5 into the measurement box 1, and is discharged from the air outlet 6 through the duct (not shown). As a result, it is returned to the air control unit 8. In addition, since ten photosensitive drums are stored in the drum storage shelf 3 in advance, hands are inserted through the working holes 4 for testing, and one drum is taken out of the drum storage shelf 3. After a while
Measurement is performed on one drum, and after the measurement, the drum is returned to the storage shelf 3 so that 10 drums under the same environment can be obtained.
Continuous measurement of books is realized.
