A sheet member feeder device includes: a sheet member housing section that houses a sheet member for feeding; a guide member, provided so as to be movable in approach-separation directions that approach towards, or separate away from, an edge of the sheet member housed in the sheet member housing section, the guide member guiding the edge of the sheet member; a restricting member that is provided to the guide member, the restricting member engaging with an engaged portion provided to the sheet member housing section and restricting movement of the guide member in the approach-separation directions; and a pressing member that, when the restricting member is engaged with the engaged portion, presses the guide member towards the sheet member by the pressing member inserting further into a gap between the restricting member and the guide member.

Sheet member feeder device and image forming apparatus

There is provided an image forming apparatus including: a photoconductor drum; an intermediate transfer belt that is wrapped around and stretched between the photoconductor drum and a plurality of support rolls and is driven by the photoconductor drum; and a contact member that contacts the intermediate transfer belt, wherein the image forming apparatus satisfies the following expression (1)2(&#x2212;1)/(+1)&#x3e;and T&#x2266;396.9 N&#x2003;&#x2003;(1),

Image forming apparatus having an intermediate transfer member wrapped around and driven by a photoconductor drum

An image forming apparatus including: a photosensitive body; a drive unit of the photosensitive body; an intermediate transfer body which is wound around the photosensitive body and is driven by the movement of the photosensitive body; a latent image forming unit; plural development units which develop the latent image on the photosensitive body with toners having different colors; a holding unit which holds the plural development units and causes the development units to sequentially face the photosensitive body; a transfer unit which transfers a toner image from the photosensitive body to the portion of the intermediate transfer body wound around the photosensitive body; and a drive speed control unit which controls the rotating speed of the photosensitive body according to the density of the toner image to be formed.

Image forming apparatus and method of transferring image to intermediate transfer body by controlling the drive of a photosensitive body

There is disclosed an apparatus for supporting evaluation of usability in consideration of situations particular to each business and ISO evaluation standards. The usability evaluation support apparatus uses an instrument including a display portion for displaying information, and supports the evaluation of usability in achieving a given task. During achievement of the task, a control unit acquires information of an operation log related to an operation performed by a user, and divides an effectiveness index associated with achievement of the task, efficiency index associated with efficiency for the achievement, and satisfaction index associated with subjective satisfaction of a task achiever for each predefined subtask. The unit evaluates the indexes by a statistical calculation using measurement results of a plurality of measurement items including the information of the operation log for each subtask.

Usability evaluation support apparatus

The present invention provides an electronic meeting system which enables a user to refer to the progress of a meeting from the user's unique view point. A first communication unit communicates information with a client. A first analysis unit analyzes the information transmitted. A first attribute extraction unit extracts the attribute included in the information. A first memory unit stores the attribute and the information in correlated relation. An information management unit manages information and extracts required information to return it to the client. A second communication unit communicates information with the sever. An input unit receives information input from a mouse. A second analysis unit analyzes input information. A second attribute extraction unit extracts the attribute included in the information. A second memory unit stores the extracted attribute. A selection unit selects a desired attribute from among attributes stored. A display unit displays the information written in the virtual space on a display unit in the form of display type corresponding to the selected attribute.
