AI Technical Summary

Technical Problem

In conventional image forming apparatuses, guide pins of the transfer unit protrude from the side plates in the left-right direction, which increases the length of the apparatus and may lead to an increase in size of the apparatus.

Method used

An intermediate transfer unit design is adopted, and disassembly and assembly are achieved by sliding in the first direction. The locking structure of the main body side guide and the unit side guide is utilized to ensure that the unit side guide does not protrude outward from the frame in the second direction. Combined with the positioning design of the driven roller and the driving roller, the length of the device in the second direction is reduced.

Benefits of technology

The length of the image forming device in the second direction is effectively reduced, thereby achieving miniaturization of the device, and ensuring reliable disassembly and assembly of the intermediate transfer unit through a stable guiding mechanism.

Abstract

The present invention provides an image forming device comprising: a device body; an intermediate transfer unit having an intermediate transfer belt and configured to be attachable to and detachable from the device body by sliding in a first direction. The device body has a main body-side guide portion that guides the intermediate transfer unit in the first direction when the intermediate transfer unit is attached or detached from the device body. The intermediate transfer unit has a side frame that includes a frame portion extending in a frame shape with the first direction as the longitudinal direction and is arranged adjacent to the intermediate transfer belt in a second direction orthogonal to the first direction; and a unit-side guide portion that engages with the main body-side guide portion. The unit-side guide portion is configured not to protrude outward from the frame portion in the second direction.
