This image forming devicecomprises an image processing unit, an HDDand an image forming unit. The image processing unitis capable of instructing the output of the image data sent from the PC. The HDDis connected to the image processing unitand is capable of storing the image data to be delivered. The image forming unit is capable of receiving the instruction from the image processing unitand delivering onto paper or the like the image data stored in the HDD. Then, when the ID information contained in the image data is detected by the image processing unit, writing of image data to the HDDis prohibited.

Image forming device and image forming system

This image forming devicecomprises a control unit, a connector interface, an external memory, and an image forming unit. The control unit instructs the output of a predetermined image data. The connector interfaceis connected to the control unit. The external memorycan be removably connected to the connector interfacewhile it stores the output image data. The image forming unit is capable of receiving the instruction from the control unit and delivering onto paper the image data stored in the external memory

Image forming device

The present invention relates to an image forming apparatus capable of reading out an image from stored data, after an image forming job has been executed, and copying the image data onto a copy paper. The apparatus reads image data on a document, stores the image data in a memory, and thereafter copies the image data stored in the memory on copy paper. The apparatus employs an operation mode switching key for switching between a normal mode and a re-output mode. Image data corresponding to a job which has been stored most recently in the memory is read out to copy the image data read out on a copy paper. This occurs when a start key is operated while the apparatus is in the re-output mode, as selected by an operation mode switching key.

In a method of adjusting image forming conditions according to the present invention, it is judged whether or not a humidity detected by a humidity sensor is not less than a predetermined first humidity H.sub.1 (step W6). As a result, when it is judged that the humidity is not less than the first humidity H.sub.1, a main charger table is accessed using the detected absolute humidity as an address, and corresponding additional data G is read out (step W7). The additional data G read out, together with additional data E and main charger driving time adjustment data F, is added to main charger reference data K.sub.2, so that main charger voltage data C.sub.2 is produced (step W8). On the other hand, when the detected humidity is less than the first humidity H.sub.1, a voltage to be applied to a main charger is not adjusted depending on the humidity.

A reset mechanism of a counter for counting the number of times of image formation is mounted on an image forming apparatus. The image forming apparatus includes a unit constituting at least a part of an image forming section which is detachably mounted on a predetermined portion of the main body of the image forming apparatus, a driving mechanism for driving the unit, and a counter for counting the number of times of image formation for reporting the time for replacement of the unit. The reset mechanism has a reset switch provided for on the main body for resetting the counter, and an operating member which is provided for on the unit for operating the reset switch. If a unit which has not been used is mounted on the main body, the operating member which is previously set in the operating position resets the reset switch. If the unit is initially driven by the driving mechanism, the operating member is moved to the operating position by the driving mechanism, so that the connection between the operating member and the driving mechanism is released. The operating member which is moved to the non-operating position can be held in the non-operating position, so that the unit never operates the reset switch.

A paper feeding device for taking out paper sheets contained in a paper containing section one at a time by a paper feeding roller to feed the paper sheets. When a paper jam occurs in the position of the paper feeding roller, the rotation in one direction of the paper feeding roller is continued, so that the paper feeding roller is returned to its home position. At the time when the paper feeding roller is returned to its home position, the rotation of the paper feeding roller is stopped, to prepare for paper jam processing. A nip portion which nips the paper sheet and a non-nip portion spaced apart from the paper sheet are located on an outer peripheral surface of the paper feeding roller. In the home position, the nip portion is not opposed to the paper sheet and the non-nip portion is opposed to the paper sheet. That is, when a paper jam occurs, the paper feeding roller is stopped in a state where it is not pressed against the paper sheet in the paper containing section.
