摘要： An infiltration amount measuring unit is provided to measure the amount of carrier liquid infiltrated in recording paper. An output signal of the infiltration amount measuring unit is input to a control device to be used to calculate a voltage supplied to a heat source (heater) in a pre-fixing unit. A signal of a paper temperature measuring unit is input to the control device, which determines whether a target temperature is reached. The control device estimates the amount of carrier liquid in a toner layer based on the information from the infiltration amount measuring unit. Then, the pre-fixing unit is controlled such that the amount of carrier liquid in the toner layer falls within an appropriate range, based on the estimation result of the amount of carrier liquid.

摘要： Provided is a development device and an image forming apparatus that realize high image quality with improved decrease in density at high speed development and with reduced occurrence of development hysteresis (ghost) in a hybrid developing method having a plurality of toner carriers, by reducing the decrease in the toner supplying ability to a downstream-side toner carrier, which decrease is caused by the supply of toner to an upstream-side toner carrier on an upstream side in a rotating direction of a developer carrier. By providing a magnetic pole between main magnetic poles, of the developer carrier, facing the toner carriers, a magnetically raised bristle of developer is moved by a magnetic force, while the developer in which development hysteresis due to supplying toner to the upstream-side toner carrier occurred is conveyed to supply toner to the downstream-side toner carrier, whereby a developer layer is stirred.
