摘要： An electrophotographic imaging apparatus includes a toner image holding body, a transcription unit for transcribing the toner image on the toner image holding body onto a recording medium, and a conveyor for conveying a recording medium toward the toner image holding body and transcription unit. A judging device will judge whether printing is of a first page or not and if it is decided that printing is to be performed on a first page, a first measuring device will measure the electrical characteristic of the toner image holding body prior to the feeding of a recording medium and a transcription voltage will be set depending of this measured result. Thereafter, the recording medium will be conveyed toward the transcription unit where the electrical characteristics of the non-printing region on the recording medium will be measured via a second measuring device and the transcription voltage will be further adjusted. If it is judged that the recording sheet is not the first sheet, only the second measuring and adjusting will be performed. In this manner, transcribing of a toner image can always be performed regardless of the kind of paper being used and/or changes in the environment (temperature, humidity) and a high transcribing efficiency can be attained.

摘要： An outer peripheral length of an intermediate transfer drum of a color laser beam printer is constituted in which a number of a beam detection signal obtained by one rotation of the transfer drum is formed as an integral number of a face number of a polygon mirror. A passing-through detection means detects the passing-through of a specified position mark on a photosensitive body belt and is provided on the photosensitive body drum at predetermined position. An image data requirement signal generating means controls a generating timing of an image data requirement signal for forming a toner image by the passing-through detection signal. A scanning line at a raster direction based on the beam detection signal after the transfer drum has rotated at one rotation returns and overlapped on a scanning line position formed on the first beam detection signal as a standard. A plural toner images having a different color each are formed on the transfer drum without color offset.

摘要： An intermediate transcription drum is supported so as to be driven in contacting relationship with a photosensitive belt. The rotating speed of the photosensitive belt driving motor is controlled by a control unit such that one rotation cycle of the intermediate transcription drum becomes a given cycle. An adjustment of the speed control data for the photosensitive belt driving motor is performed in the interval between electrostatic latent image forming. Thereby, a speed difference between the photosensitive belt and the intermediate transcription drum does not occur, and a plurality of the toner images can be transferred and accurately superposed onto the outer surface of the intermediate transcription drum.

摘要： In a serial thermal transfer printer or serial thermal printer comprising; a thermal head having a plurality of heat elements arrayed in a line; and means for selectively energizing and driving the plurality of heat elements in synchronous relation with the relative movement between the thermal head and the ink ribbon or heat sensitive paper, wherein when printing dots are successively positioned in the direction of the relative movement between the thermal head and the ink ribbon or heat sensitive paper, printing timing of the last dot is set ahead so as to be earlier than normal printing timing. When the previous printing data is "1" (recording) and the subsequent printing data is "0" (not recording), the position of the present printed dot is shifted toward the previous printed dot to compress the entire width in case of two or more successive dots. Since the printing head is traveling continuously during printing, the position of the present printed dot can be shifted toward the previous printed dot by advancing the printing timing. If the previous printing data is "0" and subsequent printing data is "1", it is apparent that a similar effect can be obtained by setting the printing timing backward so as to shift the position of the present printed dot toward the subsequent printed dot.

摘要： An apparatus for transferring toner images which is capable of executing optimum discharging control even where the environment, the material of the paper, and the kind of paper may be changed.First, the load current is detected when the transferring roller 11 is pressed to a transferring drum 6. The detected load current is converted to a characteristics detecting signal S6 at a signal converting section 109. An environment is selected on the basis of the characteristics detecting signal S6. Next, the load current flowing to the transferring roller 11 is detected when an AC discharger 14 is stopped. The detected load current is converted to characteristics detecting signal S6 at the signal converting section 109. A voltage control signal is selected based on the converted characteristics detecting signal S6, the environmental information, and the paper kind. A power source for discharging 22 is controlled by the selected voltage control signal so that the transferring becomes optimum.Accordingly, even if the kind of paper and environment is changed, optimum transferring and high transferring efficiency can be maintained.
