ない。These crystal grains, together with water vapor in the air, form local batteries with aluminum. The formation of local cells oxidizes the aluminum and causes corrosion. Particularly under hot and humid conditions, oxides of aluminum and other contained metals precipitate on the drum surface. Due to the precipitation of metal oxides,
The conductivity of the drum may decrease. for that,
When copying is performed using an organic photoreceptor formed by this drum, the residual potential of the photoreceptor increases. If the residual potential is high, fogging may occur in the copied image, making it impossible to obtain a clear image.

Set to a range of %. The higher the purity of aluminum, the less likely local batteries will form (although completely pure aluminum is too flexible, which can cause burning during the cutting process when forming the drum, which is undesirable). For example, JIS
Examples include 1000 series materials. Examples of JIS 1000 series alloys include JIS 1050 and JIS 1060. All are pure aluminum alloys, JIS
1050 has aluminum purity of 99.5% or more and electrical conductivity (IAC3,%) of 61. According to JIS 1060, the aluminum purity is 99.6% or more and the electrical conductivity is 62.
