Abstract:
An image forming apparatus includes an image holding member, a developing device, and a supplying device including a storage unit and a transport unit, wherein the storage unit stores toner and includes a bag having a flexible material, the transport unit uses suction pressure to transport the toner from the storage unit and supplies to the developing device, the toner contains an amorphous polyester resin, a toner particles has a weight average molecular weight Mw and a number average molecular weight Mn, the weight average molecular weight Mw is in the range of 25,000 to 60,000, the ratio Mw/Mn is in the range of 5 to 10, the ratio (P 2 /P 1 ) of the peak height of the absorption peak of the toner particles at a wavenumber of 820 cm −1  (P 2 ) to the peak height of the absorption peak at a wavenumber of 720 cm −1  (P 1 ) is 0.4 or less, and the ratio (P 3 /P 1 ) of the peak height of the absorption peak of the toner particles at a wavenumber of 1500 cm −1  (P 3 ) to the peak height of the absorption peak at a wavenumber of 720 cm −1  (P 1 ) is 0.6 or less.

Claim (Index 1):
An image forming apparatus comprising:\n an image holding member; a developing device that contains an electrostatic charge image developer and that develops an electrostatic charge image on the surface of the image holding member with the electrostatic charge image developer to form a toner image; and a supplying device including a storage unit and a transport unit, wherein the storage unit stores toner and includes a bag having a flexible material; the transport unit uses suction pressure to transport the toner from the storage unit and supplies the toner to the developing device; the electrostatic charge image developer contains the toner; the toner contains an amorphous polyester resin as a binder resin; and the toner has a weight average molecular weight Mw and a number average molecular weight Mn; the weight average molecular weight Mw is in the range of 25,000 to 60,000; the ratio Mw/Mn is in the range of 5 to 10; the ratio (P 2 /P 1 ) of the peak height of the absorption peak of the toner particles at a wavenumber of 820 cm \u22121  (P 2 ) to the peak height of the absorption peak at a wavenumber of 720 cm \u22121  (P 1 ) is 0.4 or less; and the ratio (P 3 /P 1 ) of the peak height of the absorption peak of the toner particles at a wavenumber of 1500 cm \u22121  (P 3 ) to the peak height of the absorption peak at a wavenumber of 720 cm \u22121  (P 1 ) is 0.6 or less.
