摘要： An image forming apparatus includes: a stepping motor arranged in a conveying path for a paper; a driver for driving the stepping motor; a current detecting unit for detecting an actual current value; and a control unit for providing a set current value for every predetermined cycle. The control unit determines an estimated load torque value corresponding to the set current value in a previous cycle and the actual current value in a present cycle, by referring to a relationship between actual current and load torque of the stepping motor with respect to the set current value, determines a target load torque value based on the estimated load torque value, and determines, as the set current value, a current value corresponding to the target load torque value, by referring to a relationship between maximum output torque of the stepping motor and current supplied to the stepping motor.

摘要： In an image forming apparatus which forms images by transferring to a transfer drum a toner image formed on the surface of the photosensitive member directly driven by a stepping motor, the relationship between the stepping angle ".theta." (.degree.) of the stepping motor and the rotational speed "N" (rpm) of the photosensitive drum is expressed by the equation .theta..ltoreq.(360.times.N)/(60.times.a.times.b). Where "a" is a natural number, optimally 10, which is less than the initial predetermined tolerance value when the harmonic content of rotational variation generated by the step period of the stepping motor is "1/a", and "b" is the target frequency (Hz) of 100.

摘要： An image copying device and an image copying system are arranged to read an image of a document and to acquire copyright information on each area regarding the image of the document from an IC chip embedded in the document. Then, based on the read image data and the acquired copyright information, a selection screen is displayed on a manipulation/display panel. Copyright information on each area of the image of the document is schematically represented on the selection screen. Whether or not copying is performed is selected area by area by manipulation by a user on this screen. For areas for which “copying” is selected is copied, but areas for which “nocopying” has been selected is not copied. Further, a copyright fee pertaining to the copied areas is collected. Thus, the image copying device and an image copying system enable the user to select appropriate processing according to differences in copyright information from one area to another of the image and cause images to be formed.
