Field of the Invention The present invention relates to an image forming apparatus, and more particularly, to a copying machine, a facsimile, a printer, and the like, in which logging data is displayed on a display unit and further printed out. The present invention relates to an image forming apparatus having a function.

[Conventional technology]

For example, in a copier, if logging data such as the number of times a copying operation is performed, the number of times a transfer paper misfeed occurs, and the number of document misfeeds can be obtained, valuable data can be obtained during repair and maintenance. And quick and accurate response can be achieved.

[Problems to be solved by the invention]

However, conventionally, it has not been considered to actively obtain the logging data, and only a few kinds of necessary minimum failure contents are displayed by characters or symbols or a warning is given only by lighting.

It is an object of the present invention to provide an image forming apparatus capable of displaying and printing out logging data.

[Means for solving the problem]

In order to achieve the above object, an image forming apparatus according to the present invention includes means for counting data such as the number of times of image forming operation, the number of times of misfeed of a recording sheet, the number of times of misfeed of a document, and the count data by the means. Initialization means for initializing each item or all items collectively, and a timekeeping means for measuring and storing the time when the initialization was performed by the means.
Storage means, output means for outputting at least one of the initialization value execution time and the current time together with the count data to a display unit or a printer, and a copy mode, a count data display mode and a printer output based on the inputted password. Mode setting means for setting any of the modes,
The counting data display mode is set by the input of the password, and in the state where the counting data display mode is set, when the image forming is not performed, the password for setting the counting data display mode is set. When a preset personal identification number different from the above is input, the output unit is enabled to output to the display unit or the printer, and initialization is permitted by the initialization unit.

[Action]

According to the above-described means, when various types of logging data are displayed, the counting time is displayed simultaneously with the display of the logging data, and when the logging data is printed out, the counting start time is displayed together with the logging data printing. At the same time, the printout time (current time) is printed. Therefore, the logging data can be displayed and printed, and its characteristics can be clearly understood. In the display of logging data, a copy mode, a count data display mode, and a count data display mode are set from a printer output mode by inputting a password, and further, the password differs from the password when image formation is not performed. This is executed by inputting the personal identification number, and can be initialized during the display mode of the logging data. Therefore, it is possible to prevent the data from being carelessly initialized.
