[0059] The following will refer to Figures 1 to 13B A color laser printer 1 as an image forming apparatus according to a first embodiment of the present invention will be described.

[0060] Such as figure 1 As shown, the color laser printer 1 has a main casing 2 . Such as figure 2 As shown, the main casing 2 accommodates the drawer unit 3 . The main case 2 is formed with a front cover 4 which can be selectively opened and closed. When the front cover 4 was opened, the drawer unit 3 could be moved in the front-to-back direction (horizontal direction) figure 2 It moves relative to the main housing 2 between the shown storage position (inner position) and the drawn-out position (outer position) out of the main housing 2 .

[0061] Unless otherwise defined, it is assumed that the color laser printer 1 is set in an orientation ready to be used and that the drawer unit 3 and the toner cartridge 11 (described later) mounted on the drawer unit 3 are housed in the main casing ...

[0142] Then refer to the attached Figure 14 to Figure 23B A color laser printer 101 according to a second embodiment of the present invention will be described. It is to be noted that the external configuration of the color laser printer 101 and the configuration seen in a central sectional side view are the same as those of the color laser printer 1 of the first embodiment described above. That is, these configurations of the color laser printer 101 are equivalent to figure 1 and figure 2 in the structure.

[0143] It is to be noted that similar components or similar parts to those of the first embodiment are denoted by similar reference symbols, and repeated description of the same configuration as that described with reference to the first embodiment is omitted.

[0144] Such as Figure 20 As shown, the color laser printer 1 includes a drawer unit 103 having a drawer frame 121 . Such as Figure 14 As shown, the drawer frame 121 includes a pair of left and right side...

Abstract

An image forming device includes a main casing, a support member, a plurality of image bearing members supported on the support member, a plurality of developing units supported on the support member, a plurality of toner cartridges detachably mounted on the support member, and a shutter closing mechanism. Each toner cartridge includes a casing formed with an opening through which toner accommodated in the casing is supplied to the developing unit and a shutter movable between an opening position at which the shutter opens the opening and a closing position at which the shutter closes the opening. The shutter closing mechanism moves the shutter of one of the toner cartridges to be replaced from the opening position to the closing position while maintaining the shutters of the remaining toner cartridges at the respective opening positions.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a laser printer. Background technique [0002] A laser printer including a process unit detachably mounted in a main housing and a toner cartridge mounted on the process unit is provided as an example of the image forming apparatus. The process unit supports the photosensitive drum and developing unit, while the toner cartridge houses toner. [0003] For example, a toner cartridge includes an inner cylinder member for accommodating toner and an outer cylinder member for rotatably accommodating the inner cylinder member. Both the inner and outer cylinder members are formed with through holes on the peripheral wall, and a handle is formed on one end surface of the inner cylinder member. A user can operate the handle to move (rotate) the inner barrel member between an open position, where the hole formed in the inner barrel member is opposite to a hole formed in the outer barrel member;...
