摘要： The developer in accordance with the present invention includes toner, and a carrier having a core material the surface of which is coated with a coating layer made of a polymer, the coating layer having a resistance value sufficient to minimize the counter electric charge remaining in the coating layer, and the toner having any of characteristic values required for preventing a counter electric charge remaining in the coating layer from being increased. The use of the developer of the present invention not only prevents the occurrence of so-called carrier scattering, to thereby prevent blanking, but also produces an image of high quality having a high initial image density.

摘要： The present invention provides a start developer wherein an output voltage of a sensor in the start developer having a particular toner density is not less than 0.9 times an output voltage of the sensor in a developer having the same toner density in a time period during which image characteristics are stabilized after repeating image formation by an image forming apparatus and is less than a threshold value at which the supply of toner is started and a method of controlling the toner density using the start developer. According to the present invention, good images can be always formed irrespective of the variation in characteristics between sensors in image forming apparatuses and from the early stage of image formation to the stable time period.

摘要： A start developer is described which includes a toner and a carrier, present in a predetermined ratio. The carrier spent amount is adjusted so that it is not less than 0.010% in terms of the amount of carbon, as measured with a carbon analyzer. With this start developer, good quality images may be formed throughout the copying operation, from the initial image forming stage to the repeated image forming stage and through the stabilized image forming stage.
