IMAGE FORMING DEVICE THAT REDUCES CONSUMPTION OF TONER USED FOR NON-PRINTING PURPOSE
摘要：
When carrying out monochrome printing, an engine unit of a printer calculates an amount of toner consumed as lubricant by a color photoreceptor according to the number of sheets to be printed (S63). When carrying out color printing, the engine unit calculates an amount of toner remaining on the color photoreceptor after the printing based on an amount of toner necessary for printing calculated from a printing rate and an amount of actually transferred toner that is calculated from the transfer rate (S65). The toner remaining on the color photoreceptor is used as lubricant, and the engine unit calculates an amount of toner by subtracting the residual toner amount from the amount of toner as lubricant calculated from the number of sheets for monochrome printing (S67), and supplies the calculated amount of toner as lubricant to the color photoreceptor when carrying out monochrome printing.
摘要（中）：

当执行单色打印时，打印机的发动机单元根据要打印的纸张数量计算由彩色感光体作为润滑剂消耗的调色剂的量（S63）。 当进行彩色打印时，发动机单元基于从打印速率计算出的打印所需的调色剂量和从传送速率计算出的实际转印的调色剂的量，计算印刷后残留在彩色感光体上的调色剂量 （S65）。 残留在彩色感光体上的调色剂用作润滑剂，发动机单元通过从调色剂量中减去残留调色剂量来计算调色剂量，作为从单色打印用纸张数计算的润滑剂（S67），并将 当进行单色打印时，将调色剂作为润滑剂计算到彩色感光体上。
