发明名称 Image forming apparatus
摘要 An image forming apparatus in which an image is formed on a recording material includes an exposure unit that forms a non-image section potential through exposure of a photoconductor at a first laser power and forms an image section potential through exposure of the photoconductor at a second laser power that is greater than the first laser power. A control unit controls an output of laser power of the exposure unit. The output of the first laser power is controlled during formation of the non-image section potential, so as to be of a first intensity at the middle of an image forming region of the recording material, and to be of a second intensity, stronger than the first intensity, at end sections of the image forming region.

主权项 1. An image forming apparatus in which an image is formed on a recording material, comprising: a photoconductor; an exposure unit that forms a non-image section potential through exposure of the photoconductor at a first laser power, and that forms an image section potential through exposure of the photoconductor at a second laser power that is greater than the first laser power; a developer carrier that forms a developer image on the photoconductor through deposition of a developer at a region, of the photoconductor, at which the image section potential is formed; and a control unit that controls an output of laser power of the exposure unit, wherein the control unit controls the output of the first laser power during formation of the non-image section potential, so as to be of a first intensity at the middle of an image forming region of the recording material, and to be of a second intensity, stronger than the first intensity, at end sections of the image forming region.
