A history recording apparatus comprises an EEPROM for storing operation history data regarding a predetermined operation performed by a label printer, and an IC socket provided on a circuit board of the label printer and detachably connectable to the EEPROM. In particular, the history recording apparatus further comprises a CPU for updating the operation history data stored in the nonvolatile memory connected to the IC socket, upon detection of the predetermined operation having been performed a preset number of times which is determined on the basis of a writing tolerance limit of the EEPROM.

A cleaning device for a photoelectrostatic copying apparatus has a cleaning blade and a cleaning roller adapted to be brought into pressing engagement with a photosensitive member to effect cleaning thereof after transfer printing. The cleaning blade is brought out of contact with the photosensitive member and the cleaning roller is either brought out of contact with the photosensitive member or has its contact pressure reduced when the apparatus is inoperative, whereby damage to the photosensitive member due to the pressing engagement of the photosensitive member with the blade and the roller can be avoided or minimized.
