Patent ID: 10324399

Abstract:
An image forming apparatus includes an image bearing member, a developing device, and an intermediate transfer member. The developing device includes a toner container containing a toner. The intermediate transfer member is charged to 3.0 nC/g or less in terms of absolute value at the surface thereof. The toner particles include a surface layer, and the brightness histogram of the toner particles has two local maximums P1 and P2 and a local minimum V between P1 and P2. P2 is derived from an organosilicon polymer. P1 lies in a brightness range of 20 to 70, and P2 lies in a brightness range of 130 to 230. The number of pixels of P1 and the number of pixels of P2 are each 0.50% or more relative to the total number of pixels. The total numbers of pixels A1, AV, and A2 each in a specific brightness range satisfy specific relationships.
