摘要： An electrophotographic image forming apparatus is capable of restriction or elimination of the occurrence of a density fluctuation, such as a lateral stripe, and thereby can enhance the image quality. The electrophotographic image forming apparatus includes a photosensitive body, exposure device for forming an electrostatic latent image on the photosensitive body, at least two developers for developing the electrostatic image in mutually distinct colors for respectively forming toner images of mutually distinct colors, a transfer device for transferring the toner images of mutually distinct colors on a printing medium in an overlapping manner, and a fixing device for fixing the toner images transferred onto the printing medium. When one of the developers is maintained inoperative, that developer is forcedly operated for a reset operation thereof.

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.

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.
