A waste developer collecting device comprising: a collecting container; a collecting opening; a conveying unit; a filter; a partition wall; and an air inlet.

Waste developer collecting device and image forming apparatus

An image forming apparatus includes: a casing; a developer having a plurality of developers and a rotational body that is rotatably supported on the casing, the plurality of developers being able to be mounted with a toner replenishment container filled with toner, and being disposed on a peripheral surface of the rotational body; a replacement door that opens the replacement hole when opened and closes the replacement hole when closed; and a pressing portion that presses the toner replenishment container that is inserted into the replacement hole into a mounting position of the developer under interlocking with a closing operation of the replacement door and mounts the toner replenishment container to the mounting position of the developer, and is fastened to the casing after mounting in a state apart from the rotation type developer.

Image forming apparatus, rotation type development unit, and toner replenishment container

An image formation apparatus for document production of reproduction which includes a plurality of paper feed trays T,-T,placed in overlapped relation at multiple stages from top to bottom wherein the length of the top-stage paper feed tray T,in the paper feed direction is formed shorter than the length of each of the paper feed trays T,-T,at lower stages in the paper feed direction, an image support,an intermediate transfer body B, and a secondary transfer device,placed in a tray upward paper feed side space Sa above the paper feed tray T,a fuser T placed in a top-stage tray side space Sb,on the side of the top-stage paper feed tray T,and an upward side space Sb,above the space Sb,and a developing unit D placed in the upward side space Sb

Compact image formation system having a plurality of paper trays

An image formation apparatus for document production or reproduction which includes a plurality of paper feed trays T1-T4 placed in overlapped relation at multiple stages from top to bottom wherein the length of the top-stage paper feed tray T1 in the paper feed direction is formed shorter than the length of each of the paper feed trays T2-T4 at lower stages in the paper feed direction, an image support 16, an intermediate transfer body B, and a secondary transfer device 31 placed in a tray upward paper feed side space Sa above the paper feed tray T1, a fuser T placed in a top-stage tray side space Sb1 on the side of the top-stage paper feed tray T1 and an upward side space Sb2 above the space Sb1, and a developing unit D placed in the upward side space Sb2.
