  • Image forming apparatus that urges cleaning blade replacement based on calculated actual linear pressure
    Patent number: 11809121
    Abstract: A control unit of an image forming apparatus calculates an actual linear pressure of a cleaning blade by taking into account, with respect to an initial linear pressure of the cleaning blade measured in advance, a linear pressure reduction based on cumulative rotation time of an image carrier, a linear pressure reduction based on cumulative non-rotation time of the image carrier, and a linear pressure reduction based on an external temperature detected by a temperature detection unit, and the control unit outputs information for urging replacement of the cleaning blade to an output unit when a linear pressure difference between the actual linear pressure of the cleaning blade and a lower-limit linear pressure of the cleaning blade calculated in advance from an abrasion amount of the cleaning blade with respect to the cumulative number of rotations of the image carrier reaches a predetermined threshold value.
