Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a sectional view showing the internal structure of an image forming apparatus 100 according to an embodiment of the present invention. In the main body of the image forming apparatus 100 (here, a color printer), four image forming sections Pa, Pb, Pc, and Pd are upstream in the transport direction ( figure 1 middle left) to configure in sequence. These image forming parts Pa to Pd are provided corresponding to images of four different colors (cyan, magenta, yellow, and black), and sequentially form cyan, magenta, yellow, and black through the processes of charging, exposure, development, and transfer, respectively. black image.

[0023] Photosensitive drums (image carriers) 1a, 1b, 1c, and 1d carrying visible images (toner images) of various colors are arranged in these image forming portions Pa to Pd. In addition, the motor 44 is driven by the belt (ref...

Abstract

An image forming apparatus includes an image carrying member, a developing device, a toner holder, a toner holder mount portion, and a locking member. The toner holder is dismountably mounted in the toner holder mount portion and stores toner for the developing device. The toner holder mount portion has a pair of side support rails supporting a side face of the toner holder. The locking member is adjacent to an end part, in the toner holder mounting direction, of at least one side support rail, and is swingable between a first position restraining mounting and dismounting of the toner holder and a second position allowing mounting and dismounting of the toner holder. The locking member, in the second position, is on the extension line of the side support rails and, together with the side support rails, guides the toner holder to and from the toner holder mount portion.

Description

technical field [0001] The present invention relates to image forming apparatuses such as copiers, printers, and facsimiles using electrophotography, and more particularly, to an image forming apparatus including a toner tank that can be attached to and detached from a main body of the image forming apparatus. Background technique [0002] In the past, in electrophotographic image forming apparatuses, the following method has been widely used: the toner concentration (or toner amount) in the developing device is detected by a toner sensor, and if the toner concentration is low (or the toner amount is ), the developing device is supplied with toner from a toner container such as a toner tank. [0003] In such an image forming apparatus, the toner container is usually replaced with a new one when the toner container is empty. However, if the toner container can be replaced while the toner remains in the toner container, the usable toner container with the toner remaining may ...
