A transport device includes a first rotary part that rotates; a second rotary part that contacts the first rotary part, that forms a pinch region where an object to be transported is pinched between the second rotary part and the first rotary part, and that rotates together with the first rotary part; and a positioning mechanism that positions the second rotary part with respect to the first rotary part. The positioning mechanism includes a swing part that supports one end portion side of the second rotary part, that is supported at one end portion side of the first rotary part, and that is swingable around a rotation center of the first rotary part; and a fixing section that fixes the swing part.

Transport device and image forming apparatus

An image forming apparatus includes: an apparatus body including an image former that forms an image on a recording material; a covering part that is provided in the apparatus body and leaves an inside of the apparatus body open by being opened in an opening direction with respect to the apparatus body; a reversing unit that is housed by the apparatus body and discharges part of the recording material on which the image is formed by the image former externally of the apparatus body, and reverses a transport direction of the recording material; and a guiding unit that is provided adjacent to a downstream side of the covering part in the opening direction, guides the recording material discharged through the apparatus body by the reversing unit, and when the covering part is opened with respect to the apparatus body, the guiding unit moves relatively with respect to the covering part in an opposite direction of the opening direction.

Image forming apparatus and recording material transport device

According to an aspect of the invention, a developing device includes a developing container that accommodates a two-component developer, a toner concentration detecting unit that detects a toner concentration of the developer by a detecting unit exposed to an inner wall of the developing container, a transport member that is disposed within the developing container and stirs and transport the developer with a transport blade having a pitch that is equal to or less than a size of the detecting unit of the toner concentration detecting unit, and a plurality of gap holding members that is provided at a position facing the toner concentration detecting unit of the transport member and holds a gap such that a tip thereof is abutted against the inner wall of the developing container.

Developing device and image forming apparatus

An image forming apparatus includes a first condition section that derives, from the density of the image detected by an image density detector, a forming condition in forming an image such that the density of the image formed comes close to a predetermined target density, a second condition section that derives, from the environmental state detected by the environmental detector, a forming condition such that the density of the formed image becomes the target density, and a stabilization section that causes, when a difference between the two forming conditions exceeds a predetermined degree, the image forming section to perform a stabilization operation which stabilizes a developing property of the developer in the developing device as compared to the current environmental state, and thereafter causes the formation of an image, the density detection, and the derivation of the forming condition by the first condition section to be performed again.

An image forming apparatus includes an image holding body, a developing device, a transfer device, a collection device, a container, and a transport member. The image holding body includes a surface on which a latent image is formed. The developing device develops the latent image into a visual image with developer. The transfer device transfers the visual image onto a transfer medium. The collection device collects the developer remaining on the surface of the image holding body after the visual image has been transferred. The container contains new developer supplied to the developing device. The image forming apparatus has a channel that has a first sub-channel and a second sub-channel. The developer flows into the first sub-channel from one of the collection device and the container and the second sub-channel from the other of the collection device and the container.

An image forming apparatus includes individually replaceable image forming assemblies forming images of different colors; a storage portion that stores time when at least one image forming assembly currently loaded into the apparatus is unloaded; a calculating portion that calculates an unloaded-engine storage period, time elapsed from when a newly loaded image forming assembly is unloaded last time to when the image forming assembly is newly loaded; and a controller that performs image quality adjustment depending on the unloaded-engine storage period calculated before the newly loaded image forming assembly is used for image formation. The apparatus receives image data of an image that contains a color other than colors that currently loaded image forming assemblies form. The apparatus forms a final image based on the image data on a sheet through image forming operations on the same sheet while at least one of the loaded image forming assemblies is replaced.
