Abstract

An image forming apparatus includes a toner case and an attachment member. The toner case has a transmission coupling. The attachment member has a drive coupling, an advance/retreat member and a lever. The advance/retreat member advances and retreats between a first position and a second position being closer to the drive coupling than the first position. The lever is moved between a first operation position to move the advance/retreat member to the first position and a second operation position to move the advance/retreat member to the second position. When the toner case is attached to the attachment member, the toner case engages with the advance/retreat member. In this time, when the lever is moved from the first operation position to the second operation position, the toner case together with the advance/retreat member approaches to the drive coupling and the transmission coupling is connected to the drive coupling.

First claim

What is claimed is:

1. An image forming apparatus comprising:
a toner case containing a toner, wherein the toner case includes:
a case main body having a discharge port discharging the toner;
one or more rotating members rotatably installed in the case main body; and
a transmission coupling connected to the rotating members; and

an attachment member to which the toner case is attachably/detachably installed, wherein the attachment member includes:
a drive coupling connec…
