An image recording device includes a pressing force adjusting mechanism that adjusts a pressing force of a developing roller that is provided by an elastic member, against a photoconductive drum. This provides for modification and adjustment of the pressing force of the developing roller that is pressed against the photoconductive drum by the biasing force from the elastic member. Consequently, even where the developing rollers have various radius dimensions or where elastic force of the elastic member changes, adequate pressing force depending on each case can be applied to the developing roller, thereby improving the recorded quality of the image recording device.

Image recording device

An image processing device includes an image scanning unit, a first paper feed cassette, and an image recording unit. The image scanning unit scans a document placed on a document scanning surface, which defines a maximum document size. The first paper feed cassette accommodates recording paper of a size up to a first size, which is the same as the maximum document size. The image recording unit records an image on the recording paper. The maximum document size is defined by a scan maximum main scanning length and a scan maximum sub-scanning length that is preferably shorter than the scan maximum main scanning length. A record main scanning direction is parallel or substantially parallel to a long side of the recording paper of the first size accommodated in the first paper feed cassette. A scan main scanning direction is parallel or substantially parallel to the record main scanning direction.

Image processing device

A paper feed cassette includes a pair of side guides, the side guides are arranged opposite to each other such that the side guides guide both side portions of the recording papers with respect to a transporting direction of the recording papers, and the side guides have a guide width adjusting mechanism for adjusting a guide width. One of the side guides is formed of synthetic resin and includes a position adjusting portion for operating the guide width adjusting mechanism, and the other side guide is formed of a metal plate.
