ある。However, in order to keep this copying machine operating in perfect condition at all times, we do not have to rely on service personnel with the above-mentioned expertise.
A method for carrying out maintenance work has been proposed. For example, there is a method of simply replacing each image forming component such as a discharger, developer, photosensitive drum, etc. included in the device with a new one, either singly or in combination (hereinafter referred to as a process kit). .

However, there is no guarantee that it will be satisfied depending on the conditions of use. For example, if the kit is used in a very dusty place or if the kit is left unattended when being replaced. There is a very small probability that, before the O process kit reaches the end of its service life, external dust may enter and adhere to the charging wires, resulting in stains on the image.
