MEMO:
At the time of primary transfer, a minute clearance is formed between the photosensitive
drum and the ITB due to a potential difference on the edge of the toner layer transferred
to the ITB, causing a discharge symptom to occur. Due to this symptom, drum memory
occurs on the photosensitive drum. the residual toner attached to the cleaning blade is
attracted to the drum memory area, causing dirt on the photosensitive drum.

Description
1) Coat the photosensitive drum surface with a thin layer of toner with the magnet roller.
2) Scrape the toner on the photosensitive drum surface with the cleaning blade.
