The present invention relates to a method and radiation monitoring device () comprising at least one radiation detector (), a memory () and a controller (), wherein said radiation detector is arranged to detect at least one type of radiation dose. The memory () comprises a number of memory positions configured to store data resulting from said detector () detection. The positions are configured to store accumulated measured dose values corresponding to consecutive real time intervals. The controller is configured to continuously compute mean radiation dose values for measured and stored radiation doses during the predetermined time period and for each computation, a resulting mean value is compared with a corresponding predetermined reference value and generate a signal corresponding to result of said comparison.

Radiation meter and method

An air flow is generated in a space adjacent to the toner control member , when an image is not being formed, and also a cleaning electric field for moving the toner away from the toner control member is generated in the same space. For instance, a slit is formed in an outer peripheral section of a cylindrical and rotatable counter electrode member , and an air flow generating source such as a fan is connected to the counter electrode member . A convex cleaning electrode is formed around the slit of the counter electrode member , and a voltage for forming a cleaning electric field is applied from the power supply source for cleaning to this cleaning electrode
