摘要： In an electrophotographic copying machine, image quality is improved by suppressing phenomena such as narrowing and thickening of a linear image or discharge noises in a photograph image due to anomalies on transfer of a toner image. For example, a document type is discriminated and when a transfer brush is used for transfer, transfer current and pretransfer erasing are controlled according to the type of document image. The pretransfer erasing is controlled in various following situations: Bi-level exposure method or multi-level exposure method, edge emphasis, photoelectric efficiency, the surface potential of the photoconductor, and position of a developing device.

摘要： An unfixed toner image of a reference pattern is formed on a photosensitive member, the unfixed toner image is measured by a development density sensor 13, and the amount of toner to be supplied to a developing device 4 is controlled by a toner supply control unit 60 on the basis of a measurement output, thereby maintaining the image quality constant. If it is judged from a result of a detection of a state amount such as the temperature and the humidity by a state amount sensor 19 that there is a fear that the image quality exceeds an allowable range, a fixed image of a reference pattern is formed on a record medium such as a banner sheet, and the fixed image is measured by an optical sensor 10. Operation amounts such as the charge amount and the exposure value of an image output unit 100 are controlled by an image density control unit 20, thereby maintaining the image quality to be within the allowable range.

摘要： A method for controlling a transfer bias in an image forming apparatus using an electrophotographic process to prevent front and rear ends of a paper from being contaminated by inversely charged toner. The image forming apparatus applies a second positive bias voltage having the intermediate level between a transfer voltage and a first positive bias voltage for cleaning the inversely charged toner with respect to the front and rear ends of the paper. In this manner, it is possible to prevent an electric shock on the photosensitive drum due to an abrupt voltage difference between the transfer voltage and the first positive bias voltage.
