PROBLEM TO BE SOLVED: To provide an image forming apparatus that can prevent a deterioration in quality of an image due to an external additive in a toner.SOLUTION: The value of loss elastic modulus E" of a cleaning blade 35 is defined as 1.60×10[Pa] to 2.01×10[Pa] when measured at 70°C and 3.60×10[Pa] to 7.70×10[Pa] when measured at 100°C, so as to suppress an event in which an external additive added to a toner passes through a cleaning blade 35 to a degree not affecting the quality of an image to be transferred to a sheet P, and thereby achieving an image forming apparatus that can prevent a deterioration in quality of an image due to the external additive in the toner.SELECTED DRAWING: Figure 8 |
