摘要： In an image forming apparatus in which positioned below a development unit for accommodating a toner is an exposure unit that writes to a photosensitive drum by exposing an electrostatic latent image, an aperture portion on an upper surface of an exposure unit case positioned in an optical path of light from the exposure unit is provided so as to not become an impediment to the optical path of the light and a glass plate is inclined and provided on the aperture portion. An inclination angle of the glass plate is set to an angle inclined 40° with respect to a horizontal line so as to be greater than a repose angle of the toner when the toner has poor fluidity under a condition of high temperature and high humidity.

摘要： A discharge unit is disposed downstream of a principal transport path of a compound machine, and a shifter function is provided in this discharge unit. By shifting the paper passage position relative to a photosensitive drum when printing the front side and the paper passage position relative to the photosensitive drum when printing the back side, the region in which the surface electric potential of the photosensitive drum increases is diminished, and the region in which photographic fog is generated is made smaller. Thus, when printing the second and subsequent sheets, even when a slight amount of displacement of the transport position of the recording paper occurs, it is possible to suppress that recording paper making contact in the photographic fog region on the photosensitive drum, and defective printing can be prevented.
摘要翻译：放电单元设置在复合机械的主输送路径的下游，并且在该排出单元中设置有换档功能。通过在打印背面时相对于感光鼓打印前侧和纸张通过位置时相对于感光鼓移动纸张通过位置，感光鼓的表面电位增加的区域减小，产生摄影雾的区域变小。因此，当打印第二张和后续的纸张时，即使发生记录纸的输送位置的轻微位移，也可以抑制在感光鼓上的摄影雾区域中的记录纸接触，并且打印不良可以防止。

摘要： For an electrostatic latent image formed on an image carrier (31b), besides an operation forming an “image forming electrostatic latent image” used to form the primary image, an operation is executed that forms an “electrostatic latent image for removing developer” for removing developer that resides on a developer supply member (53a) for a predetermined time period onto the image carrier (31b). Thus, developer is nearly eliminated from residing on this developer supply member (53a) in an overcharged state for a long period of time, and generation of a fogged image is avoided as much as possible.

摘要： An image forming apparatus including a pair of rollers that rotate, that selectively carries out forward direction transport and switchback transport, including a guide member provided at a downstream side from the rollers in the forward direction transport that moves to either a first position or a second position, and a control portion causing the guide member to move to the first position during the forward direction transport and causing the guide member to move to the second position during the switchback transport. The first position is a position in which the guide member is retracted from a path of the recording paper on a downstream side from the rollers in the forward direction transport. The second position is a position in which the recording paper sandwiched between the rollers can be received on the guide member.
