Abstract:
An image forming apparatus includes an image carrier that includes a conductive substrate, and a photosensitive layer and a surface protection layer; a developing device that includes an electrostatic image developer containing a toner, and develops the electrostatic image to form a toner image. The toner contains an amorphous polyester resin and has a weight average molecular weight Mw in a range of from 25,000 to 60,000, and a ratio of the weight average molecular weight Mw to a number average molecular weight Mn (Mw/Mn) is in a range of from 5 to 10. In the toner, a ratio of an absorbance for a wavelength of 1500 cm −1  to an absorbance for a wavelength of 720 cm −1  is 0.6 or less, and a ratio of an absorbance for a wavelength of 820 cm −1  to the absorbance for a wavelength of 720 cm −1  is 0.4 or less.

Claim (Index 1):
An image forming apparatus comprising:\n an image carrier that includes a conductive substrate, and a photosensitive layer and a surface protection layer disposed on the conductive substrate in that order; a charging device that charges a surface of the image carrier; an electrostatic image forming device that forms an electrostatic image on the charged surface of the image carrier; a developing device that includes an electrostatic image developer containing a toner for electrostatic image development, and develops the electrostatic image on the surface of the image carrier to form a toner image; a transfer device that transfers the toner image onto a recording medium; and a cleaning unit that cleans the surface of the image carrier by a cleaning blade contacting the surface, wherein:\n the toner has a binder resin containing an amorphous polyester resin; \n a tetrahydrofuran-soluble component of the toner has a weight average molecular weight Mw and number average molecular weight Mn determined from gel permeation chromatography, and the Mw is in the range of 25,000 to 60,000, and Mw/Mn is in the range of 5 to 10; and \n the toner has absorbance measured by infrared absorption spectrometry, the ratio of absorbance for a wavelength of 1500 cm \u22121  to absorbance for a wavelength of 720 cm \u22121  is 0.6 or less, and the ratio of absorbance for a wavelength of 820 cm \u22121  to absorbance for a wavelength of 720 cm \u22121  is 0.4 or less.
