PROBLEM TO BE SOLVED: To surely and easily judge the recycle of an electrophotographic photoreceptor. SOLUTION: After an electrophotographic photoreceptor 4 in an initial state is used and collected for recycle, when using it again, a check mark is written in the part of '1' on the numerals of a recycle time display part 20. When next using it again, '2' in the numerals on the recycle time display part 20 is checked and further '3' is checked. Thus, by watching the check mark, a recycle worker can judge how many times the electrophotographic photoreceptor 4 is recycled. |
