An object of the present invention is to provide a compound that can be used as a more superior therapeutic agent for central nervous system diseases. The present invention provides a dihydrate of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or of a salt thereof, and a process for producing the same.

Dihydrate of benzothiophene compound or of a salt thereof, and process for producing the same

An image forming apparatus including: an output image forming section for forming an image and a pattern on a supporting medium under a prescribed condition; an output section for transferring the formed image on a recording sheet; a correction section for performing reading of the formed pattern and correcting the condition based on a result of the reading; and a correction control section for controlling operations of the output image forming section, the output section, and the correction section, wherein the correction control section identifies whether or not an area where the image is to be formed and an area where the pattern is to be formed overlap each other, and when the areas are identified that they do not overlap each other, the correction control section controls the output image forming section to simultaneously form the image and the pattern in parallel on the supporting medium.

Image forming apparatus

An image forming apparatus including: a first and a second photoconductor groups constituted of one or more photoconductors respectively; a first and a second drive control sections for controlling the drive of the first and the second photoconductor groups respectively to rotate the photoconductors thereof, wherein the rotational phases of the first photoconductor group and the second photoconductor group are adjusted to be matched therebetween; and the first and the second drive control sections control so that predetermined profile of a target speed is applied to the first and second photoconductor groups wherein, in the target-speed profile, the first photoconductor group starts rotating after a elapse of a predetermined startup delay time from the second photoconductor group starts rotating, and both groups end at a same final speed predetermined for full-color image formation, wherein the startup delay time is predetermined based on measurements of times needed for each of the first and the second photoconductor groups to reach a predetermined speed from starting the rotation with the target-speed profile being applied thereto.

Image forming apparatus having phase control of photoconductor groups

It is an object to prevent distortions and deviations of images caused by the eccentricity of a driven gear mounted to a rotational shaft of a photosensitive drum. There are provided a driving gear which is secured to a rotational shaft of a rotational driving power source and is rotated at a constant peripheral speed, a driven gear secured coaxially to a rotational shaft of a cylindrical-shaped photosensitive member, a phase control gear having the same diameter as that of the driven gear and having the same rotational speed variation characteristic as that of the driven gear, and a transmission gear, and a driving force from the driving gear is transmitted to the driven gear through the phase control gear and the transmission gear.

Photosensitive-member driving mechanism

A cleaning device is provided with a cleaning unit () disposed downstream from a position at which a toner image is transferred to a paper. The cleaning unit () is provided with a cleaning blade () for scraping off residual toner attached to an image bearing member and a toner catching sheet () for preventing the residual toner or paper dust which have been scraped off from falling outside the cleaning unit. The free length in the toner catching sheet () between affixed positions of a first end portion which is affixed to the cleaning unit () and a second end portion which abuts an outer circumferential portion of the image bearing member is determined by an amount of paper dust buildup on the outer circumferential portion of the image bearing member.

Cleaning device for an image forming apparatus

An image forming apparatus including: image forming sections, each image forming section forming an image of a color component among plural color components under a predetermined condition, and forming a pattern of each color component for adjusting the condition; a detecting section that reads the formed patterns so as to perform a temporary detection and a main detection of a deviation from a reference under the condition; and a correction control section that determines whether the deviation of the temporary detection exceeds a predetermined threshold value or not, and when the deviation exceeds the threshold value, executes the main detection to fully detect the deviation so as to correct the condition, wherein the correction control section controls to form the pattern for the temporary detection, the number of the color components for the temporary detection being fewer than those of the patterns to be used for the main detection.
